| 摘 要： | 滇东地区生态地质环境脆弱，石漠化明显，面积28 320 km2，严重地制约着地区经济的可持续发展。采用三级标准划分石漠化等级，景观差异特征明显，便于野外识别，制定与之相适应的整治措施。滇东地区石漠化分布具有集中连片、自北向南逐渐增多、程度加重的特点。石漠化的成因：地貌的演化过程中存在着石漠化的潜势，广泛分布的岩溶石山是形成石漠化的物质基础，特定的自然地理环境是导致石漠化的基本条件；人口增长过快、不合理的土地开发、工业污染是形成石漠化的主要因素，但自然因素和人为因素的主次因地而异。

| Abstract: | The ecologic and geologic environment is very frail and the rocky desertification is very obvious（the desertification area is 28 320 km2）in East Yunnan. The continuous development of local economy is affected seriously. We use three grade standard to classify the rocky desertification. The landscape difference is obvious, enough to take control measures correspondingly. The rocky desertification region is gathered by several small desertification regions from the north to the south and the desertification degree in south is higher. The genesis of rocky desertification is that there is rocky desertification potential with geomorphic evolutional precess, that karst mountains are material base of rocky desertification and that the local natural geographic environment is the fundamental condition. The main factor of rocky desertification is fast population growth, unreasonable exploiting of land and industrial pollution. In some places, the natural factor is the main factor, but in other places, the artificial factor is the main factor. |
