基于GIS的石漠化区域光伏项目建设适宜容量估算 —以镇宁县、紫云县及关岭县为例

该文利用卫星遥感技术，采用30米DEM及16米GF1号卫星遥感数据，选取安顺市镇宁县、紫云县及关岭县区域内坡度、坡向及石漠化情况进行卫星遥感反演。结合气象站点日照资料，运用ArcGIS软件对三个县石漠化区域光伏利用潜力分布进行空间分析，计算光伏项目建设适宜容量，得到光伏电站建设的空间适宜性分布。通过研究表明，关岭县适宜建设面积为149.6km2，占总面积42.3%，镇宁为85km2，占24%，紫云占33.7%，适宜建设面积为119.1km2；三个县总适宜装机容量达3315.9万千瓦，其中关岭为1402.5万千瓦，镇宁为796.9万千瓦，紫云为1116.6万千瓦。精细化提取石漠化区光伏建设适宜区域并定量估算装机容量，能够为该区域进行太阳能资源开发提供科学依据

Estimation of suitable capacity of photovoltaic project in Rocky Desertification area based on Gis: A case study of Zhenning, Ziyun and Guanling in Anshun

In this paper, satellite sensing technology, the satellite remote sensing data of 30m DEM and 16m GF1 are used to retrieve the slope, slope aspect and rocky desertification in Zhenning, Ziyun and Guanling for the satellite remote sensing retrieval. Based on the sunshine data of Meteorological Station, the spatial distribution of PV utilization potential in rocky desertification area of three counties was analyzed by ArcGIS software, the suitable capacity of PV project was calculated, and the suitable suitability distribution of photovoltaic power station construction is got. The research shows that the suitable construction area of Guanling country is 149.6 km2, accounting for 42.3% of its total area, Zhenning is 85 km2, accounting for 24% of its area, Ziyun is 33.7%, and the suitable construction area is 119.1 km2. The total suitable installed capacity of the three counties is 3315.9 million kw, of which Guanling is 1402.5 million kw, Zhenning is 7.969 million kw, Ziyun is 1116.6 million kw. Precise and detailed extraction of the suitable area for photovoltaic construction and quantitative estimation of the installed capacity can provide scientific basis for exploiting solar energy resources in rocky desertification area.
