Ecological level space zoning planning control method for urban and rural ecological planning

Abstract

The invention discloses a method for quantitative zoning by utilizing an ecological level space. The method comprises the following steps of: conducting an investigation and survey on geological class factors, hydrologic class factors, plant class factors and land utilization class factors in a target area; determining weight values of the geological class factors, the hydrologic class factors, the plant class factors and the land utilization class factors by using an analytic hierarchy process; superposing the geological class factors, the hydrologic class factors, the plant class factors and the land utilization class factors by using a GIS (geographic information system); carrying out weighted average on the geological class factors, the hydrologic class factors, the plant class factors and the land utilization class factors to obtain a geological class factor region picture, a hydrologic class factor region picture, a plant class factor region picture and a land utilization class factor region picture; carrying out unique treatment on the geological class factor region picture, the hydrologic class factor region picture, the plant class factor region picture and the land utilization class factor region picture and then carrying out merger treatment to obtain the ecological level space, thus completing the quantitative zoning on the target area.

Description

technical field [0001] The invention relates to a method for quantitative partitioning by using ecological level space. Background technique [0002] Urban and rural ecological planning is an ecological planning for the professional technical system of urban planning. The planning control method of ecological level space partition in urban and rural ecological planning is a spatial ecological control method for urban and rural ecological planning, especially for the professional technical system of urban planning. [0003] This is because the ecological value functions of different grades of urban areas not only result in differences in ecological values, but also differences in ecological functions; while the natural ecological protection system around cities is determined based on natural systems, the same level of zoning has convergent ecological value functions.

Problems solved by technology

[0004] Defects of existing technical solutions: According to the "Interim Regulations for Ecological Function Zoning Technology" issued by the State Environmental Protection Administration, the ecological function zoning is based on the sensitivity of the regional ecological environment, the importance of ecological service functions, and the similarity and difference of ecological environment characteristics. geospatial partition of

The results of comprehensive ecological analysis cannot be used in the technical system of urban planning only by the zoning system of ecological function zoning
