| 摘 要： | 云南地处中国西南石漠化中心地区，从石漠化的影响因素展开全省石漠化分区的定量分析研究对促进石漠化治理及生态环境保护和可持续发展具有深远意义。运用主导因素法和叠置法，依据地形、气候条件、地带性土壤、植被等综合因素对云南65个石漠化县域进行区划。将云南省65个石漠化县域分为7个区域10个亚区19个小区，7个区域分别为北热带低山河谷盆地石漠化区、南亚热带中低山河谷盆地石漠化区、中亚热带高原山地石漠化区、北亚热带高中山石漠化区、暖温带高中山石漠化区、青藏高原东南缘高原温带石漠化区和金沙江燥热河谷石漠化区。本研究提出的云南省石漠化区域划分新体系，是从粗放的宏观区划向精细区划迈进的创新成果，这一区划成果使石漠化地区综合治理技术设计更具有可操作性。

| Abstract: | Yunnan is located in the center of rock desertification area in southwest China. It is of great significance to carry out the quantitative analysis of rocky desertification distribution in the whole province, in order to promote the treatment of rocky desertification, ecological environment protection and sustainable development. Dominant factor method and superposition method were used to divide 65 rocky desertification counties in Yunnan, according to the comprehensive factors such as landform, climate, soil and vegetation. Results showed that 65 rocky desertification counties in Yunnan Province could be divided into 7 areas, 10 subregions and 19 districts. 7 areas included North Tropical Low Mountain Valley Basin Rocky Desertification Area, South Subtropical Medium Low Mountain Valley Basin Rocky Desertification Area, Central Asia Subtropical Plateau Mountain Rocky Desertification Area, North Subtropical High-medium Mountain Rocky Desertification Area, Warm Temperate High Medium Rocky Desertification Area, Temperate Rocky Desertification Area on the Southeast of Qinghai-Tibet Plateau, and Jinsha River Dry Hot Desert Valley Rocky Desertification Area. The new system of dividing rocky desertification areas in Yunnan Province proposed in this study is an innovative achievement from the extensive macro division to the intensive division. The results of this division make the technological design of comprehensive treatment of rocky desertification more operational. |
