Research on Functional Zoning of Karst Land System at County Regional Scale Based on the Methods of Lattice and ANN
摘要
Abstract
Karst land resource is one unique class of land resources,that only overall planning and rational partition can safeguard its sustainable use.Du′an typical Karst land system was selected as an rearch object.Based on the theory of regional land ecology,economy and society function development,with the data of 2009 related construct totally 16 evaluations on natural resources,social and economic etc.According to the nature of indicators,standardize the indicators with the utility function,then,by using the method of lattice,Du＇an land system was divided into 313 grid cells,the regional functions were evaluated according to BP neural network technology.Finally,the results were displayed in the form of the map.The results show that the Du＇an karst land system can be divided into 4 functional zones such as ecological environment restoration zone,protective development zone,ecological and economic co-ordination zone and humanity built-up zone.Based on the function zones,the land use direction can be ensured reasonably,and the efficiency of the county land resources allocation can be maximized,the land use action can be sustainable.This partition method is more scientific and the result is more objective,which can provide a reference for land use activities of other karst areas,however,the selection of indicators should be further improved.关键词
