【摘要】 以遥感数据、气象观测与土壤调查数据作为分析背景,结合膏桐生长对气候、土壤与坡度等因素的要求,采用农业生态区法和社会经济因素限制法,开展云南膏桐种植重要地区的适宜性评价。传统的地面调查方法,不仅工作量大、周期长,而且精度不高。利用空间技术(遥感技术、地理信息系统和全球定位系统)针对农作物的分布和面积进行数字化定量研究,旨在探索一种区域农业生产监测与评价的技术方法。更多还原

【Abstract】 The main objective of this paper was to introduce space-based technology in key areas of Yunnan and the potential of Jatropha curcas survey methods to choose the technology appropriate lines,as government and business-related decision-making and related research provide a scientific basis.Remote sensing data,meteorological observation and analysis of soil survey data as a background,combined with the growth of Jatropha curcas on climate,soil and slope requirements and other factors,the use of agro-ecological zones and socio-economic constraints Law Act,to carry out important areas of cultivation of Jatropha curcas in Yunnan appropriate evaluation.The traditional ground survey methods,not only a heavy workload,long cycle,and accuracy was not high.This use of space technology(remote sensing technology,geographic information systems and global positioning system) for the distribution of crops and area of digitized quantitative study to explore a regional monitoring and evaluation of agricultural production technology and methods.更多还原
