| 摘 要： | 根据影像的色调和纹理特征,获取研究区的草地植被覆盖特征信息与喀斯特石漠化分布信息,并利用定位观测、野外样地调查进行验证,建立喀斯特石漠化环境下草地遥感调查解译标志,进而利用"3S"技术,通过对石漠化环境下草地相关数据分析,实现对喀斯特环境下草地分布的遥感调查及其在石漠化地区分布的空间相关性分析。并根据三都水族自治县喀斯特地区草地空间分布现状,提出了对草地石漠化的防治建议。

| Abstract: | According to the color and texture features of image,the information of grassland vegetation cover features and karst rocky desertification distribution was acquired,and then verified through positioning observation and field survey,the interpretation sign of grassland RS investigation under karst rocky desertification environment was established.Through analyzing the related grassland data in karst desertification environment with the "3S" technology,a correlation analysis was conducted on the RS investigation on grassland distribution and its distribution in rocky desertification area.According to the grassland distribution status in Sandu Shui Autonomous County,some control measures of grassland rocky desertification were presented. |
