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、紫云县和关岭县为例

Estimation of Suitable Capacity of Photovoltaic Project Based on GIS in Rocky Desertification Area:A Case Study of Zhenning,Ziyun and Guanling

该文利用卫星遥感技术,采用30 m DEM及16 m GF1号卫星遥感数据,选取镇宁县、紫云县和关岭县区域内坡度、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3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149.6 km^(2),占总面积42.3%;镇宁为85 km^(2),占24%;紫云为119.1 km^(2),占33.7%;3个县总适宜装机容量达3315.9万kW,关岭、镇宁、紫云分别为1402.5万kW、796.9万kW、1116.6万kW。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。

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 km^(2),accounting for 42.3%of its total area,Zhenning is 85 km^(2),accounting for 24%of its area,Ziyun is 33.7%,and the suitable construction area is 119.1 km^(2).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.
