| 摘要: |
| 为确定昆明市空间布局，利用最小累积阻力模型和ArcGIS的空间分析方法，对昆明市全域的土地生态适宜性进行评价分区。结果表明：1）昆明市生态保护核心区面积为7 032.11 km2，占全区面积的34.75%，为基本农田保护区和生态红线保护区，对保证粮食安全、维护生物多样性及水源涵养具有重要作用；2）昆明市生态保护涵养区面积为4 444.31 km2，占全市面积的21.15%，集中分布在北部的东川区、寻甸县、禄劝县以及富民县；3）生产生态扩展区面积为7 711.87 km2，占全市面积的36.70%，主要分布在建设开发区外围，包括禄劝县西南部，富民县东北部和西南部，寻甸县西南部，东川区东部，石林县东南部，晋宁县，西山区等地；4）建设开发核心区面积为1 554.98 km2，占全市面积的7.40%，集中分布在昆明市的都市核心区。 |

| Abstract: |
| To determine the spatial layout of Kunming,the land ecological suitability of Kunming is evaluated and divided by using the minimum cumulative resistance model and the spatial analysis method of ArcGIS.The results show that:1) The area of ecological protection core area of Kunming is 7 032.11 km2,accounting for 34.75% of the total area.Basic farmland protection areas and ecological red line protection areas play an important role in ensuring food security,maintaining biodiversity and water conservation;2) Kunming's production ecological protection and conservation area is 4 444.31 km2,accounting for 21.15% of the city's total area,which is concentrated in Dongchuan District,Xundian County,Luquan County and Fumin County in the north;3) The area of production ecological expansion area is 7 711.87 km2,accounting for 36.70% of the city's total area,which is mainly distributed in the periphery of the construction and development zone,including the southwest of Luquan County,the northeast and southwest of Fumin County,southwest of Xundian County,east of Dongchuan District,southeast of Shilin County,Jinning County,Xishan District,etc.;4) The core area of construction and development is 1 554.98 km2,accounting for 7.4% of the city's total area,which is mainly distributed in the urban core area of Kunming.This study combines the anti-planning method with the minimum cumulative resistance model to provide reference for the spatial planning layout of Kunming. |
