The Eco-Economic Regionalization Based On Grid Technique

With the rapid development of economic, the contradictions between ecological environment and economic construction become more and more obvious.So it is very necessary to locate the eco-economic function for every region according to socio-economic and environmental features and study on eco-economic regionalization.But the traditional regionalization can't consider the location all directionally and multi-levelly, such as social,economic and resources aspects,and can't guide the coordinated development of such aspect precisely. Most regionalization take the township as unit to calculates the relevant indicators,so the result can't break through the boundaries of administrative regions and not be in conformity with the actual situations of the region.Some index,such as population density, per capita GDP index failed to allocate to grids.So it has important practical significance to study theory and technology of eco-economic regionalization profoundly. According to ecological economics and the theory of sustainable development,under the guide of system theory,the composite index used for zoning is divided into base values in the paper and a set of index system on zoning is established,which include ecological,social,economic, resources and environment aspects.To increase the accuracy of zoning,the study area is divided into equal grid connected closely. Take the grid as unit to calculates the base values one by one in support of grid technique, especially allocate the population density, per capita GDP index to grids,then calculates the upper indicators gradually until get the composite index,and divides the study area according to it.Applide the grid technique in the zonihg of Yuanqu Shanxi Province and investigated the practical situation to verify the result which shows that the division is rational and testified the actionability and rationality of the zoning method.
