Qinling Effect In Taiping River Plain Study Section Of The Plant Community Configuration Mode

In recent years,due to many kinds of unreasonable development and construction,the ecological resources of north Qinling in Taiping river basin have suffered serious destruction.River banks and the pollution cause plant community of the river corridor gradually degraded,which affects the north Qinling in the virtuous cycle of Taiping river ecosystem. Because that the related researches in the head river area are more than the river area in the middle and tail, so there is a huge meaning in studying on these areas. The vegetation as the most important natural rivers "background",plays an important role in the maintenance of river ecosystem stability, meet the ecological function and form the local characteristics of landscape culture. Because the river is the natural of element intensive, humanity and ecology process sensitive area, so it is very important in making the most of ecology in the process of ecological benefit, social benefit and economic benefit under the dual role of natural and human disturbance.Therefore,it should be scientific and reasonable to the destruction of river corridor near nature, build for north Qinling Taiping river plain river corridor plant configuration mode.Firstly, in this context of Qinling Taiping river natural geographical environment,water, plants, land, mineral resources in the forest were demonstrated briefly this paper.Selects typical and relatively stable plant community in Taiping river plain of Qinling,which is combined with the special geographical environment in Taiping river plain of Qinling.Analysis the north Qinling Taiping river plain section of the plant community on both sides of the present situation by reading literature, combined with the research methods of on-the-spot investigation.including species composition,community types, community structure and vegetation distribution,and proved northQinling Taiping river plain section of the plant community configuration mode,under the guidance of plant ecology theory.Secondly, according to the basis of the above researches and analysis, from the species composition, community structure, configuration mode of Taiping river area in the middle and tail reaches of the river, and analyzing the specific issues to explore the causes of differences, use the method of scientific comprehensive evaluation Taiping river river plain of he north Qinling in section of plant community, reveal the Taiping river plain of north Qinling section of the present problems of the plant community configuration modes:the singleness of tree species,the simpleness of community structure、canopy structure and the simpleness of structure level.Finally, through the research, in view of the Taiping river plain of north Qinling concrete situation, find out its internal problems, based on the principles of optimization,construct solutions to Taiping river plain section of the plant community configuration mode: increase local tree species in the study area,improve the species composition of plant community and the structure of plant community,make the plant community more stable;Enhance the high value and the proportion of dominant species and native species,improve the naturalness of plant community; increases the levels of the artificial community and the specification of the number of native trees, improve the coverage of plant community,highlight the structure of plant community, pay attention to the individual number of high,medium and low grade plants and species distribution profiles;artificial plant community is required more perfect in plant community structure level the,adjusting the ratio of different plants in the community density,improve the diversity,richness,evenness and the structure of the vertical natural degrees of artificial plant community, in order to achieve the stability of plant community, and build a variety of functional plant community configuration mode.
