摘要
以贵州省典型岩溶石漠化地区为例,采用不同时相的TM多光谱数据和19个基准地面气象观测站及自动站1999—2013年的逐日降雨数据为数据源,以遥感(RS)、地理信息系统(GIS)为技术手段和平台,1999—2013年的年均降雨量和年暴雨频率为评价因子,运用地统计学和空间信息分析方法分析岩溶石漠化与大气降雨的关系。结果表明:降雨(非暴雨)是加剧岩溶石漠化进程的因素之一,也是减缓岩溶石漠化进程的重要因素;暴雨加速了岩溶石漠化的演化进程,对岩溶石漠化的恢复起反作用。
Taking the typical karst rocky desertification area in Guizhou Province as an example,TM multispectral data in different time phases and daily rainfall data from 1999 to 2013 in 19 basic ground meteorological observation stations and automatic stations as data source,remote sensing( RS) and geographical information system( GIS) as technical means and platform,the average annual rainfall and rainstorm frequency from 1999 to2013 as evaluation factors,the relationship between karst rocky desertification and atmospheric precipitation is analyzed by the method of geo-statistics and spatial information analysis. The results show that rainfall( non storm) is one of the factors that aggravate the karst rocky desertification process. It is also an important factor in slowing the karst rocky desertification process. Rainstorm accelerated the evolution process of karst rocky desertification,and it was counterproductive to the recovery of karst rocky desertification.
