摘要
种植适宜性评价的目的是在充分评价土地潜力的基础上 ,合理利用自然资源 ,进而优化生产布局。GIS技术是正在被广泛应用并具有强大空间分析能力的高新技术 ,与种植适宜性评价模型结合 ,可充分发挥地图化表现和空间分析能力。本研究以ArcView为GIS工具 ,建立了基于多元线性回归算法的种植适宜性评价系统。并以澜沧江下游地区 96个乡 (镇 )为基本评价单元 ,对 14种热带特色经济作物进行了评价 ,生成了相应的专题地图 ,对种植适宜性的空间分布规律进行了分析。表 2 ,图 3,参 3。
The suitability assessment system for cash crops production was developed for the comprehensive utilization of natural resources and the optimization of the crops production structure.As a widely used hi tech with a powerful function of geo analysis,GIS demonstrated its potential in map visualization and spatial analysis after combined with suitability assessment models.In this project ArcView was used and the suitability assessment model of multivariate linear regression was developed.For 96 basic assessment units of villages/towns in downstream areas of Lancang River,Yunnan Province,China,the suitability of 14 tropic cash crops was assessed,the assessment result were mapped and the spatial distribution of crops'suitability was analyzed
