中文摘要	为进一步提高石漠化综合治理水平,利用3S-CAD技术对广西天等县岩溶小流域石漠化综合治理工程进行初步设计.设计以RS技术对基础地理信息进行解译,以GIS对信息进行数字化,管理,分析和输出,以GPS对样地等进行定位,以CAD技术进行工程制图,并以小山流域石漠化综合治理设计为例,通过提取该流域的数据信息并进行空间分析,然后结合野外实地考察,确定其石漠化综合治理工程主要由封山育林,人工造林,水利水保,草食畜牧组成,其中,封山育林805hm2,人工造林46hm2,水利水保工程引水渠7 462m,草食畜牧业面积330m2.工程总体布置点线面相结合,林草植被工程,水利水保工程和草食畜牧业工程分布配套,与传统的方法相比,3S-CAD技术具有设计速度快,工程布局科学合理的特点
英文摘要	In order to improve rocky desertification treatment in karst areas,a preliminary design for Tiandeng County in Guangxi is made by means of the 3S-CAD technique. The design,a case in the Xiaoshan Small Watershed, comprises the RS in interpreting the basic geographic information, the GIS in digitizing, managing, analyzing and outputting the data, and GPS in locating the sample plot during field survey and the CAD in carrying on engineering drawing. According to the design and field survey,it is determined that the comprehensive treatment of rocky desertification mainly includes forest conservation(805hm2 of hillside), reforestation(46hm2 of land), diversion canal for water conservancy(7 462m long) and forage grass planting(330m2of land). General arrangement of the project adopts the combination of sub-projects in small patches of land, line-formed land and overall layout on the whole area, which enables the reforestation and water conservancy as well as animal husbandry projects support with each other. Compared with the traditional methods, the 3S-CAD technique is characterized by speedy design and scientific and reasonable layout for project
