摘　　要：选择具有温凉春干夏湿岩溶高原山地生态环境的毕节市鸭池示范区作为研究对象,应用5 m分辨率的Spot 5遥感影像、1∶1万地形图、土地利用图等基础图件,对示范区进行了石漠化遥感解译,对不同土地利用类型的石漠化发生情况进行了定量研究。研究结果表明,石漠化土地中以灌木林地、其它林地、低覆盖度草地、陡坡耕地和裸岩石砾地等土地利用类型所占比例较大。土地利用类型的差异性是导致石漠化发生程度差异的因素之一,石漠化治理不仅要实现保护和改善生态环境,还要结合示范区人口社会经济情况,提高土地的生产力,采取以坡改梯为重点的工程措施、以经济林种植为主的生物措施进行综合防治。Yachi demonstration Base in Bijie region,where has a karst plateau hilly environment setting with warm and cold temperature ranges,dry springs and humid summers,was chosen as the study area.Based on Spot 5（5 m resolution） remotely sensed images,the topographic maps（1∶10 000）,and the land use map,etc.,the extent of rocky desertification in this area were interpreted and the incidence of rocky desertification in the different types of land use were investigated quantitatively.It was found that the spatial distribution of different land use types is one of the important factors that lead to different grades of rocky desertification.Shrubs,other forests,low-coverage grassland,mountainous dry land,and unused land contributed a large proportion of the desertified land.In addition to protecting and improving ecological environment,enhancing the productivity of the land and developing the social economy should also be listed as the major objectives in deploying integrated measures for the rocky desertification control.For example,engineering measures like terracing project should be constructed combining with biological measures such as economic trees planting,etc.
