Studies On Ecological Effects Of Land Use Planning At Country Level

Land use structure and spatial layout is always in dynamic process of change under the common influence, which are both natural process and human activities. The land use change are both objectively recorded extent changed the earth surface features of space layout by human and, emersion the landscape dynamic changing process that the surface of the earth space-time. At present The Land Use/Cover changes (LUCC) is one of the core themes for global changing researcher. This paper referenced landscape ecology theory and method, only study human activities on a new round of land use planning of landscape space pattern changes through geographical information system (GIS) technology. Discuss land use will impact ecological environmental of country in the future. It is important significance that executed the new round of land use planning, which will coordinate economic development of backward small town and Protection of good comprehensive ecological environment value resources. Specific research contents include following aspects:(1) Land use status in 2005 and every year using accounts make as basic data and materials. We make a scheme after considered that the trend of Chun'An Country economic development and confirmed the important degree in Hangzhou, then class landscape types and draw them by geographical information system (GIS) technology.(2)In this part, it focused on analysis of landscape pattern, which is about land use planning of Chun'an country. Patch analyst is an extension to the ArcGIS software system that facilitates the landscape spatial analysis of landscape patches and the modeling of attributes associated with patches. It is used for spatial pattern analysis. It is run in the ArcGIS environment. The quantitative analysis of landscape characteristics and them changes and then we can reach a decision which is a trend of landscape space pattern changes of on a new round land use planning, and analysis of landscape structure change process, It is the key point that considering the cultivated protection and construction land development in the land use planning process. It is mainly concentrated expression in woodland, waters, farmland and land for construction purposes of MPS changes.%PLAND is increase that Farmland and use the land for construction, farmland increase are relatively obvious, the garden is the biggest decline It is advantage landscape in the study areas. Landscape types have diversification and equalization direct to the development trend of tend to be more complicated, the shape of patch.(3)In this part, it focused on analysis of ecological service value, which is about land use planning of Chun'an country. According to the value ecosystem services methods of Costanza and Xie Gaodi's units of the Chinese terrestrial ecosystem service value coefficients. Analysis of the land use planning of county-level of ecosystem service value of change forecasts. Analyzing Chun'an of ecosystem service value of change in grid by classical geological grid method, basis on these, divided theâ… ,â…¡,â…¢,â…£andâ…¤five levels.
