Although increasing precipitation may cause vegetation changes, few studies have explored the linkage between alteration in vegetation and WUE. Here, we analyzed the responses of leaf WUE, ecosystem carbon and water exchanges, ecosystem WUE, and plant community composition changes under normal conditions and also under extra 15% or 30% increases in annual precipitation in a temperate desert ecosystem of Xinjiang, China. We found that leaf WUE and ecosystem WUE showed inconsistent responses to increasing precipitation. Leaf WUE consistently decreased as precipitation increased. By contrast, the responses of the ecosystem WUE to increasing precipitation are different in different precipitation regimes： increasing by 33.9% in the wet year（i.e., the normal precipitation years）and decreasing by 4.1% in the dry year when the precipitation was about 30% less than that in the wet year.We systematically assessed the herbaceous community dynamics, community composition, and vegetation coverage to explain the responses of ecosystem WUE, and found that the between-year discrepancy in ecosystem WUE was consistent with the extent to which plant biomass was stimulated by the increase in precipitation. Although there was no change in the relative significance of ephemerals in the plant community, its greater overall plant biomass drove an increased ecosystem WUE under the conditions of increasing precipitation in 2011. However, the slight increase in plant biomass exerted no significant effect on ecosystem WUE in 2012. Our findings suggest that an alteration in the dominant species in this plant community can induce a shift in the carbon-and water-based economics of desert ecosystems.展开更多

As an important part of the junior high school teaching system, this point is no exception. Based on this, how to realize the "burden reduction and increase efficiency" of junior high school Chinese teaching has become an urgent problem for the majority of teaching workers at the present stage. The following closely follow the above topics, first analyze the significance of "reducing burden and increasing efficiency" of junior high school Chinese teaching under the new curriculum reform, and then explore the strategy of "reducing burden and increasing efficiency" of junior high school Chinese teaching, hoping to provide favorable reference.展开更多

As an important energy source for the economic development of our country, petroleum and chemical industry in our country is developing continuously with the progress of the society. At present, the petroleum and chemical industry in our country has gradually stepped into the forefront of the world. As a kind of non-renewable resources, oil is an important resource formed by the earth's geological process for thousands of years. Nowadays, the increasing demand for oil resources in the international community has resulted in the depletion of oil resources and the difficulty and complexity of oil exploitation projects. Therefore, under the current social environment of shortage of oil resources, effective measures must be taken to comprehensively enhance the geological exploration in the later stage, so as to fully cover the production benefits of oil field exploitation. This paper will sort out and analyze the geological potential tapping and efficiency enhancement in the later stage of oil field development.展开更多

On the one hand, teachers need to reduce students' learning pressure and schoolwork burden. On the other hand, they also need to actively construct an efficient classroom, so it is very critical to mobilize students' interest in learning. Teachers need to give students more opportunities to learn independently, stimulate students' learning initiative, so that students can truly learn by doing and play in learning, and then find their own geography learning strategies and skills. In this regard, based on the actual conditions of junior high school geography education and teaching, the relevant strategies and requirements to reduce the burden and increase the efficiency of the subject are understood, which will provide a certain reference for the promotion of junior high school geography teaching reform.展开更多

Therefore, we should do a good job in financial management innovation, master the corresponding methods in the construction of management accounting tool system, and solve the actual problems, so as to ensure the smooth development of enterprise management accounting. In addition, to seriously study the laws of our country, we should take the enterprise itself as the starting point, strengthen the understanding of the knowledge related to management accounting, and finally realize the maximization of the interests of the enterprise.展开更多

However, the development of offshore fluvial reservoirs is faced with the problems of thin reservoir thickness, narrow plane width, rapid lateral change, and thin well pattern. Taking the KLA oilfield as an example, this paper discusses the nuanced characterization and configuration of a single channel controlled by sedimentary facies to guide developing offshore river facies’ narrow channel main control oilfield. Firstly, based on a large number of core data, the acceptable sedimentary facies identification is realized, the sedimentary model of the study area is established, the delicate calibration of logging facies and seismic facies is realized under the constraint of the sedimentary model, and a set of technical methods for nuanced reservoir characterization guided by seismic sedimentology is summarized, to realize the boundary identification of composite channel configuration and further realize the nuanced characterization of the single narrow channel. Based on this set of technology, it guides the smooth implementation of horizontal wells in the oilfield. The drilling encounter rate of the reservoir in the horizontal section of the single well exceeds 90%, ensuring the injection production connectivity and increasing the reserve production rate by more than 10%.展开更多
