摘要
利用地理信息技术及气候资源信息,对内蒙古乌盟地区的主要农作物马铃薯做了多项自然资源空间统计分析,并选定了该地区马铃薯种植的气候区划指标和风险指标。这些指标涉及到马铃薯的种植失败风险和减产风险。利用小网格资源推算法,实现了基本气候资源分布的细化。同时借助于CITYSTARGIS的二次开发功能,用VisualC++编制模型,进行马铃薯气候资源区划和种植风险程度区划的地理制作。研究结果可供农业种植规划部门及农业保险部门使用。
This paper presents a means for dividing the agricultural climate districts and harvest risk districts of potato based on GIS technique and climate resource information.The indicators of climate and risk which includes the fail and lost risks for potato growing in the county WulanCabu in the middle of Inner-Mongolia Autonomous Area are given according to the spatial statistic results of multi-natural resources in the county.Meanwhile a prediction method of natural resources distribution on small grids is applied to all cases chosen here.Using CITYSTAR 3.0,the agricultural climate districts and the harvest risk districts are drawn and shown in geographical maps.The district maps can be provided to the Department of agricultural planting and planning and the Department of agricultural insurance for helping them in district choosing.
