摘要
为合理估算云南、贵州两省可利用坝区,并了解其空间分布,利用云南、贵州两省DEM及土地利用数据,综合考虑生态敏感性、生态服务功能、生态风险多种生态空间制约,并叠加土地利用情况,合理估算两省适宜开发的坝区.结果表明,云南贵州两省适宜开发的土地面积较少,分别为2575.1,1011.0km2,仅约占国土面积的1%,主要集中于滇中、黔中地区.
To estimate the area and spatial distribution of available flatland in Yunnan and Guizhou provinces, the constraints of ecological sensitivity, ecological service function and ecological risks to current land use pattern and DEM （digital elevation model） were introduced. The results suggest that only about 1% of the territorial areas of Yunnan and Guizhou provinces was physically and ecologically suitable for development in 2010. Most available flatlands were distributed in central Yurman and Guizhou regions, respectively.
