The evaluation system was divided into four layers, including the target layer, the comprehensive layer, the element layer, and the index layer. Each layer was made of different indices. The evaluation standards for each index were also given in this paper. This evaluation model was proved tenable through its application to the landscape design rationality evaluation of the Weihe River in Xinxiang City of Henan Province. The results show that the water quality, space, activity, facility, community, width of vegetation, sense of beauty and water content are among the most influential factors and should be considered the main basis for evaluating the rationality of the landscape design of urban rivers.展开更多

Five methodological factors（sample dehydration,extraction solvent,extraction duration,number of extractions,and ratio of solvent volume：sample weight） were studied using an L 9（3 4 ） orthogonal design in a sedimentary pigment extraction experiment on samples collected from the Changjiang large-river delta-front estuary（LDE）,using HPLC analysis. The results show that the optimal extraction method for sedimentary pigments should include freeze-drying samples prior to extraction. The effects of different factors on sedimentary pigment extraction were separated by the L 9（3 4 ） orthogonal design experiments and showed that the extraction solvent was the most important,with extraction duration the second most important,and numbers of extraction and ratio of solvent volume：sample weight was the least important. The mixed solvent treatment comprised of acetone,methanol and water（80：15：5,by volume） was best for polar pigment extraction,with 100% acetone better for apolar pigments. For most pigments employed in this study（i.e.,peridinin,fucoxanthin,alloxanthin,diatoxanthin,zeaxanthin,pheophytin-a and β-carotene） ,3 h was found to be enough time for extraction from these deltaic sediments. However,for chlorophyll-a,the most important pigment used for estimating algal biomass,12 h was needed. A small amount of solvent（3 ml） with duplicate extractions obtained the greatest amount and diversity of pigments. Unfortunately,no extraction method was found to be suitable for all pigments in sediments. The choice of extraction procedure should be made in accordance with the objective of each study,taking into consideration the properties of sediments and pigments in question.展开更多

Plant landscapes of Longwanggang River were oriented as riverfront landscape belt with multiple textures, urban portal and ecological corridor, aiming at returning to the nature, integrating environmental resources, achieving large scales and multiple forms. Considering properties of the neighboring plots, functional areas are divided according to different community types and eco-community structure of the plant landscapes, so as to form landscape nodes, highlight overall plant landscape effects, regional characteristics and low maintenance cost.展开更多

The concept of ecological water conservancy requires that river planning and design should be scientific and reasonable, and follow the concept of ecological water conservancy. In order to effectively improve the water quality and ecological efficiency of watercourses, the concept of ecological water must be incorporated into the safety principle. So as to realize the construction of ecological water conservancy project. In order to ensure the normal drainage, navigation and drainage of waterway, it is necessary to design the waterway bed in a scientific and reasonable way, improve the ecological environment, create a good ecological environment for the waterway, improve the efficiency of water projects and consider the needs of life and ecology to improve the function of the project.展开更多
