| With the rapid development of urbanization,the game between city and rural,as well as rural ecology gradually being "invaded",leads to habitat being eroded,ecological land being tattered. According to the national requirements for the construction of ecological civilization,as well as the needs of transformation and upgrading in economic and social development of Jiangsu province,or taking the point of view from the unique ecological role in the east Lake Taihu Basin,Wujiang,the development of "Great Ecology" pattern seems quite necessary and urgent,ecological space pattern will be the general direction of future development.This study is conducted to explore some actual problems currently existing in the ecological environment in SuNan Water Network-Intensive,as the study object,Protecting and optimizing the ecological environment through the ecological, planning and policy perspective,coordinating the relationship between spatial distribution and the network of ecological environment,exploring to constructe the pattern and evaluation methodolgy of ecological space in SuNan Water Network-Intensive,optimizing the strategies and safeguard measures of ecological spacial pattern. A case study of SuZhou WuJiang Area,in order to avoid the costly construction and renovation,as well as the cost of ecological restoration during the disorderly development of ecological environment in the process of urbanization. The ecological environment of water grid in Wujiang District is one of the typical areas in the south of Jiangsu Province with dense water network,there are some practical reference value for network-intensive areas in the south of Jiangsu in the pattern research for the study on the ecological spacial pattern,and that there is direct guiding significance for the government decision making in sustainability of ecological environment,healthy and harmonious development in the south of Jiangsu,to provide theoretical and practical basis for the spacial pattern of the ecological environment suitability in the dense water network area in south of Jiangsu,to offer advice for the sustained,healthy and harmonious construction of urban-rural integration in the south of Jiangsu.This study differentiates the related concepts of Ecological Spacial Pattern,analyzes its development process,and defines the concept of ecological spacial pattern. It deepens the knowledge thoroughly on ecological spacial pattern with the research progress at home and abroad from two aspects--ecological space and spatial pattern. The study constructs the model of ecological spacial pattern based on the theoretical basis such as Planning of Green Infrastructure,network theory,source- sink theory. The model is composed of "Extraction of influential elements--Construction of element mechanism--Selecting construction methods--The evaluation of results". The study makes full use of spatial analysis technology in the GIS platform,combined with Conefor Sensinode2.2 and other softwares,and does a scientific comparative analysis on the status quo and the prediction of the ecological spacial pattern,in Wujiang District, Suzhou,thereby,to establish the optimization pattern based on the advantage of both. On the basis of which, the study advises on space optimization strategy and the implementation of the planning for the future development of ecological spacial pattern in Wujing District,Suzhou.A good ecological spatial pattern is the management of growth in urban space,as well as the boosting for resources and environment with economic growth. It plays a role as a "compass" in the land development for the cities and towns in south of Jiangsu. Not only it is conducive to the intensive and development purposiveness of land,but also ensures the achievement of a win-win good state between the development and expansion,along with the safyty of ecosystem. |
