Atlas Analysis of spatiat-temporal evolution of Karst Rocky Desertification in LuoDian County Based on GIS and RS Technology——Taking Luodian County of Guizhou Province as an Example
摘要
Abstract
[Objective] The research aimed to study spatial-temporal evolution in karst rocky desertification areas of Guizhou Province.[Method] Based on the software platform of Erdas9.2 and ArcGIS9.3,this research used Tupu of geoinformation as a theory and method,analysed Tupu of 2005 and 2014 described spatial-temporal evolution in Karst rocky desertification area at LuoDian County.[Result] The change of rocky desertifi cation degrees are very greatly from 2005 to 2014.The biggest increases was mild rocky desertification,its increasing area was 264.38 km2,accounted for 8.8% of the total area,which mainly derived from moderate rocky desertification and mild rocky desertification.The second increases was moderate rocky desertification,its increasing area was 89.04 km2,accounted for 2.96% of the total area,which mainly derived from mild rocky desertification.Tupu units of rocky desertification degrees reduced the most is no obvious rocky desertification.The types of potential rocky desertification and mild rocky desertification belong to the most unstable degrees.[Conclusion] Accordingly,from 2005 to 2014 the strength of Luodian County's rocky desertification degrees have been aggravated and gradually changed from mild rocky desertification to intensity rocky desertification.关键词
