摘要:
为了掌握平塘县灌木林情况,通过 3S 技术结合贵州省第四次森林普查和第二次国土普查数 据,分析了平塘县灌木林的空间特征和组成结构。结果表明:灌木林占了平塘县国土面积的 23.24%,灌 木林主要分布在平塘的中部、南部以及西南部,其中卡罗乡和鼠场乡灌木面积最多,分别占了国土面积 的 49.90% 和 48.41%;平塘县灌木林种以水土保持林为主,其次为薪炭林;国家特别规定灌木林地占平 塘县灌木林的绝大多数;灌木林起源主要以天然林为主。另外平塘县灌木林的空间分布和组成主要受自 然因素影响,尤其是喀斯特地貌,人为因素促进了平塘县植被的生长和生态环境治理。

Abstract:
In order to grasp the shrubbery forest situation in Pingtang county, through 3S technology combined with second-class investigation and Guizhou forest census data, The spatial characteristics and composition of shrubbery in Pingtang county are analyzed. The results show: shrubbery covers 23.24% of Pingtang county’s land area, shrubbery is mainly distributed in the middle, south and southwest of Pingtang, among them, the shrubbery in caro and rodent field are the largest.
