Considered the status quo in plant ex conservation, a nutritional strategy on the plant conservation was proposed based on ＇Ecological Similarity＇. Its main idea was that the ex-situ conservation plants coming from natural ecosystem were compulsively allocated in the agro-ecosystems and would return to natural ecosystem ultimately. Therefore, research on plant nutrition of the ex-situ conservation plants should neither just pursue yield and quality as that in agro-ecosystems nor merely stay on intrinsic natures without human intervening. We should give attentions to both of their attributes as in natural ecosystems and in agro-ecosystems, i.e., taking full advantage of plant nutritional measures as in agro-ecosystems to solve actual survival problems of the ex-conservation plants, and ensuring the final goal of returning to nature and playing its ecological role.展开更多

Thisstudy aims to evaluate the ecological, social, economic, institutional, and infrastructural sustainability of the Maros–Watampone road corridor that crosses TN Babul. Using a qualitative descriptive design, the research employed theMultidimensional Scaling (MDS) method supported by leverage and Monte Carlo analysis. Data were gathered fromkey stakeholders through purposive sampling and analyzed based on sustainability attributes across five dimensions.The findings reveal that environmental, institutional, and infrastructure dimensions scored in the "less sustainable"category, indicating high ecological risk and governance gaps. In contrast, economic and social dimensions weremoderately sustainable, reflecting emerging opportunities for inclusive growth. Sensitive attributes influencingsustainability include habitat fragmentation, road design, governance coordination, and community participation. Thestudy concludes that balancing development with conservation requires integrated, multi-stakeholder strategies andtargeted interventions that address the most vulnerable sustainability dimensions.展开更多

In this process, enterprises have played an important role in optimizing the economic growth, promoting energy-saving and emissionreduction, and spreading ecological culture. The paper analyzes the present situation and existing problems of current construction of ecological civilization of enterprises in China. On the basis of current situation of the construction of ecological civilization of enterprises in Beijing and in line with the industrial standard of CRISP-DM, the paper utilizes decision tree algorithm and researches the key elements which infl uence the enterprises' willingness of the construction of ecological civilization. The research result shows that there are three key elements which infl uence the enterprises' willingness of the construction of ecological civilization: enterprises' average sales of the past three years, the categories of enterprises and enterprises' principals' cognition on the responsibility of the construction of ecological civilization; other two variables have no infl uence on the willingness: the ration of research and construction staff in enterprises and that whether enterprises are high-tech ones. Therefore, it is necessary that governments should take the lead to establish strong conception of ecological civilization among citizens, carry out vigorously the publicity and education of the construction of ecological civilization, enhance the cognition levels of enterprises' principals and reduce the costs of the construction of ecological civilization.展开更多

The per capita share of forestry resources is relatively low. With the rapid development of economy and urban construction, the insufficient protection of forestry resources has also led to the decline of forestry resources which has a very negative impact on the ecological environment. However, in recent years, with the increasing awareness of ecological environment protection, the importance of sustainable development of forestry economy has been fully recognized. It can be said that when the forestry economy develops steadily, it will also promote the local economic construction and improve the living standard of local residents. In the new development period, we should fully coordinate the development of forestry ecological environment protection and forestry economic construction, improve the level of forestry economic construction and further promote the development of forestry ecological environment protection.展开更多

文摘The survival strategy of plants is to adjust their functional traits to adapt to the environment.However,these traits and survival strategies of evergreen broad-leaved forest species are not well understood.This study examined 10 leaf functional traits(LFTs)of 70 common plant species in an evergreen broad-leaved forest in Huangshan Mountain to decipher their adaptive strategies.The phylogenetic signals of these LFTs were assessed and phylogenetically independent contrasts(PIC)and correlation analyses were carried out.LFTs were analyzed to determine their CSR(C:competitor,S:stress-tolerator,R:ruderal)strategies.The results show that plant species exhibit different leaf functional traits and ecological strategies(nine strategies were identified;the most abundant were S/CS and S/CSR strategies).Some traits showed significant phylogenetic signals,indicating the effect of phylogeny on LFTs to an extent.Trait variations among species suggest distinct adaptation strategies to environmental changes.The study species were mainly clustered on the C-S strategy axis,with a high S component.Species leaning toward the C-strategy end(e.g.,deciduous species),favored a resource acquisition strategy characterized by higher specific leaf area(SLA),greater nutrient contents(N and P),lower leaf dry matter content(LDMC),and reduced nutrient utilization efficiency(C:N and C:P).Conversely,species closer to the S-strategy end(e.g.,evergreen species)usually adopted a resource conservative strategy with trait combinations contrary to those of C-strategy species.Overall,this study corroborated the applicability of the CSR strategy at a local scale and provides insights into the varied trait combinations and ecological strategies employed by plant species to adapt to their environment.These findings contribute to a better understanding of the mechanisms involved in biodiversity maintenance.

With the ecology view, there is consistency between strategic network and strategic ecosystem. Enterprise should pursue for suitable ecological niche to hold a strategic competitive power.
文摘Based on the perspective of ecological concept,this study first interpreted the background of ecological civilization construction,and combed the relationship between ecological concept and small town planning.Second,it expounded the ecological problems of natural resources,economic development,landscape system,social humanities and other aspects in the construction of contemporary small towns.According to the study,the construction of small towns based on the ecological concept should establish the concept of "ecology first",practice "multiple compliance",coordinate the relationship with other planning,make reasonable planning and design in the aspects of town scale,functional orientation,structural form,road traffic,landscape style and features,humanistic characteristics,and strengthen the implementation,supervision and management of planning.Finally,summary and outlook was made,hoping that the study will be of reference value and guidance to the planning and construction of small towns.
文摘Slope ecological protection technology is a form of slope protection with high ornamental and good economic value.At present,it is widely used in highways and urban streets’slope protection works.However,its use is not very common in mountain tourism highways;hence,it is necessary to implement strategies for mountain tourism highway slope ecological protection design to promote excellent development.
文摘The ecological civilization in the new age is one important aspect for undergraduates.We must enhance the concept of their civilization and improve the quality of civilization.Carrying out ecological civilization education in colleges and universities has a practical significance for enriching the contents of ideological and political education to realize their all-round development.Nowadays,some undergraduates lack awareness of ecological civilization and ignore its importance.For this reason,undergraduates need to pay attention to ecological civilization and improve their own ecological civilization literacy to promote the all-round development in qualities in the new age.This paper mainly analyzes the current problems in undergraduates’ecological civilization education and explores effective strategies to solve the current problems in undergraduates’ecological civilization education.The strategies include integrating ecological civilization resources,innovating methods of ecological civilization,strengthening ecological educator team construction,embodying ecological culture in campus construction and creating the atmosphere,emphasizing innovative practices for ecological civilization,strengthening publicity of social-ecological civilization,and attaching importance to family education of ecological civilization.
文摘China has a vast territory, but forestry resources are relatively scarce and the distribution is uneven. The per capita share of forestry resources is relatively low. With the rapid development of economy and urban construction, the insufficient protection of forestry resources has also led to the decline of forestry resources which has a very negative impact on the ecological environment. However, in recent years, with the increasing awareness of ecological environment protection, the importance of sustainable development of forestry economy has been fully recognized. It can be said that when the forestry economy develops steadily, it will also promote the local economic construction and improve the living standard of local residents. In the new development period, we should fully coordinate the development of forestry ecological environment protection and forestry economic construction, improve the level of forestry economic construction and further promote the development of forestry ecological environment protection.
