Research On Analyzing Of The Landscape Pattern And Planning Practice In The XI’AN-XIANYANG Region Of The Wei River

With the establishment of XiXian new area, the urban construction range hasextended to the Wei River and the city development has changed from river "back" toriver "forward", what’s more, the Wei River also altered to "the city river". In theprocess of transformation, the Wei River space will face large-scale development andconstruction on both sides, compared to the course of construction of the urban river,the Wei River should pay more attention to the river’s ecology and watershed, while thewaterfront area building into the urban green space system to meet the urban functionsof the river.This paper selects the Wei River in the urbanization as the research object. Afterthe basic research and site investigation both sides of the Wei River, this paperelaborates that Wei River is an important ecological corridor river in the west to eastdirection of the GuanZhong district, and is also an important ecological barrier in thenorthern part of Xi’An, an development spindle of XiXian new area and ribbon of greenspace for recreation. This paper puts forward the core issues to be solved: give priorityto the premise of the Wei River ecology, how to build the Wei River ecological corridorlandscape spatial structure, the Wei River to better urban functional area connection,how to deal with the connections of Wei River and the city which is to maintain thebalance of the Wei River ecological system protect, urban flood safety and effective useof waterfront.This paper solves the problem from three aspects. In theory, the paper makesresearch of river corridor general structure and the basic principle of ecologicalprocesses from the theory aspect, and compound of landscape ecological security pattern recognition step in the ecological processes, then discusses constructionexperience and enlightenment in the urbanization progress in Xi’An range andtributaries of waterfront according to the development strategy of Wei River. In thestudy of cognitive, this paper makes the analysis of landscape situation and takes thelandscape pattern analysis method to Wei River corridor landscape characteristicspresent situation from the natural process, biological process and human process,summarizes the landscape type and existing problems of XiXian part of Wei Rivercorridor. In problem-solving strategies, this paper establishes the landscape securitypattern model from the river and beaches, waterfront space and native plant habitats,and Taiwan tableland terraces and town city construction district four aspects, then putsforward "the heterogeneity of layer" mode and "wedge penetration" mode, anddetermine the width of each layer to provide the theoretical model for planning practice.Finally, according to the research content, this paper takes the Wei river ecologicallandscape zone planning as an example, makes a comprehensive demand of the Xi’angreen space system construction in the macroscopic level, puts forward land usepatterns, planning strategies for protection and display of ecological sensitive areas andhistorical and cultural landscape of Xixian region of Wei river in the medium level, thenraises landscape planning ideas of waterfront leisure space in the micro level. This papermakes a systematic summary of core problem solution from top to bottom, and hascertain application value of Wei river ecological landscape construction.
