【摘要】："城镇上山"是云南近年来为保护为数不多的坝区优质耕地而实施的重大战略,空间资源的规模、位置等是城镇上山的基础。本研究在认识滇东高原不同地貌小区地理环境特征和识别城镇上山地理环境约束条件的基础上,利用RS和GIS技术,获取相关地理环境信息并进行空间分析。结果表明,滇东高原城镇上山的空间资源总量为217.23km2,且与城镇化发展趋势及要求在空间上大致吻合,即城镇化发展迅速、城镇上山需求量大的原上缓丘盆地小区和斜坡台地丘陵小区空间资源量较大。但城镇上山空间资源相对较为分散,连片分布斑块不多且面积不大。这意味着滇东高原城镇上山战略的推进,可节约的优质耕地数量是相当可观的,但上山过程中的山地整理任务仍十分繁重。
[Abstract]:It is an important strategy to protect a few high quality cultivated land in dam area in Yunnan province in recent years. The scale and location of space resources are the basis of mountain climbing in cities and towns. Based on the understanding of the geographical environment characteristics of different landforms in the eastern Yunnan Plateau and the identification of the constraint conditions of the urban mountain geography environment, the relevant geographic environment information was obtained and the spatial analysis was carried out by using RS and GIS techniques. The results show that the total amount of space resources in the cities and towns on the eastern Yunnan Plateau is 217.23 km2, which is roughly consistent with the development trend and requirements of urbanization, that is, the rapid development of urbanization. There is a large amount of spatial resources in the original upper gentle hill basin and slope terrace hilly area, where there is a high demand for mountain in cities and towns. However, the spatial resources of urban mountain are relatively scattered, the patches are not many and the area is not large. This means that the promotion of mountain strategy in the eastern Yunnan plateau town can save a considerable amount of high-quality cultivated land, but the task of mountain consolidation is still very heavy.
