Study And Practice On The Ecological System Planning Of Guanzhong Plain In Shaanxi

With the development of social and economic and people’s living standards improving,the environment and development issues has plagued human. Natural ecosystems to theservices and support functions of human survival and development are facing a serious threat.It is not only making regional environmental quality degradation, but also accelerating thefrequency of occurrence of natural disasters and hazards of strength, which in turn restricts theeconomic and social development. Guanzhong as the most powerful and dense citiy in thewestern region, has the huge potential to promote economic and social development of theGuanzhong area even the Northwest. It is necessary to develop the sustainable Eco advancely.Therefore, the start Guanzhong Plain forestry ecological system planning studies, theobjective requirements of the development of the times, but also to build a harmonious society,to jointly promote ecological civilization era call.Summarizing and analyzig the ecological planning were at home and abroad and basingon the analysis of Guanzhong, according to rivers, roads, the basic situation of ecologicalintegrated district of Guanzhong Plain and according to landscape ecology "Matrix, plaques,corridor,"the basic principles for the future development of the Guanzhong Plain forestryconstruction,we will put forward the corresponding countermeasures, not only for theGuanzhong area serve as a reference, but also for the entire Northwest region forestryecological system planning for the development of ideas.In this thesis, the following conclusions:(1)Basing on the principle of Ecological Planning Division and local conditions, theGuanzhong Plain ecological complexes of partition can be divided into six other areas,Linyou-Chunhua loess low mountain shelter area; Weibei tableland dry grain, apples, sheltergreen "ocean" area; Weibei high ground grain, oil, cotton area; Wei river to farmers, workers,deputy, trade in dense urban areas; Lishan hilly landscape shrub grass area; Weinan alluvialfan base and tableland dry land, famous fruit area.(2)Analyzig the Guanzhong Plain in the natural and environmental conditions analysisbased on the Guanzhong Plain rivers, roads, the basic situation of ecological integrateddistrict and according to landscape ecology "matrix, patch, corridor," the basic principles,weput forward in the Guanzhong Plain ecological system of "one axis, two rings, three horizontal, seven vertical and five Area, around ten Shuilv Gallery Guanzhong" ecologicallandscape pattern ideas.(3)From an ecological corridor concept, combining the Guanzhong area’s uniquegeographical and cultural conditions in the Guanzhong area，it is suitable to drawn roadconstruction and river ecological corridor at least not less than7m.(4)According to green corridor from the river, traffic green corridors, forestry ecologicalsector, agriculture, forestry and other ecological landscape mixing matrix elements, wediscussed aspects of building the Guanzhong Plain ecological system and ecologicallandscape pattern vision techniques and methods.(5)Combining with the actual situation and analysing carefully, we proposed to build theGuanzhong Plain ecological system of the four strategies, not only for the Guanzhong areaserve as a reference, but also for the entire Northwest region forestry ecological systemplanning for the development of ideas.(6)We should use native species when we choose the road greening. In addition, it isimportant to combine shelterbelts, twelve roads surrounding green corridors, economicfunctions, cultural functions and ornamental features into account, and then to play aprominent ecological and production function.
