摘　　要：在土地利用现状以及喀斯特空间分布的基础上,通过利用GIS技术初步划分茶叶种植适宜地和不适宜地;并选择对茶叶生长相关的地貌、气候及土壤条件中8个评价因子,通过专家打分确定其权重,应用GIS空间分析模块实现贵州茶园生态适宜性评价。结果表明:贵州适宜茶叶种植的面积为3.241 7万km2,占国土面积的18.40%;其中非常适宜茶叶种植的区域面积为1.061 8万km2,主要分布于黔东南、黔北、黔南以及黔中地区;适宜茶叶种植的区域面积为1.155 4万km2,全省均有分布;比较适宜茶叶种植的区域面积为1.024 5万km2,主要分布于黔北、黔西北、六盘水以及黔西南等区域;不适宜种植茶叶的区域主要分布于贵州喀斯特强烈发育,石漠化严重的地区。Based on land use situation and karst area features, this paper divided suitable area and unsuitable area for tea planting using GIS technology. 8 ecological evaluation factors including landform, climate conditions and soil conditions were selected and the weights of each factor were worked out through expert evaluation to make ecological evaluation based on spatial analysis of GIS. The results showed that the suitable area of tea planting was 32 417.00km2, accounting for 18.40% of land area in Guizhou province. The most suitable area was l0 618. 00km2 distributing in southeast, north, south and middle of Guizhou province; Suitable area was 11 554.00km2 distributing in vast majority county; Basically suitable area was 10 245.00km2 distributing in north, north west, southwest and Liupannshui of Guizhou province. Unsuitable area distributed in rocky - desertification areas in Guizhou province. The evaluation outcomes provided a scientific basis and technology foundation for green tea industry development.
