【摘要】 本文在分析柑橘大实蝇Bactrocera minax(Enderlein)生物学特性基础上,得出影响宜都大实蝇空间分布差异主要因素为影响大实蝇蛹越冬的12月至次年2月份表层土壤温度差异、影响大实蝇羽化的5月份表层土壤湿度差异和大实蝇栖息地——桔园周围树木的空间分布差异,本文成功运用多源遥感数据和GIS空间分析技术将影响柑橘大实蝇生境的这些要素量化,结合GPS数据和对柑橘园蛆果率的调查,采用遥感的监督分类获取了宜都柑橘大实蝇适生区与非适生区的空间分布,结果很好的诠释了山区大实蝇危害严重而平原地区大实蝇危害轻的原因,为小尺度、多要素适生区分析提供一种新的方法。更多还原

【Abstract】 Based on analyzing the biological characteristics of Bactrocera minax(Enderlein),resulted that the main factors that influence the Bactrocera minax(Enderlein) spatial distribution is the difference of soil surface temperature at pupal stage from December to February of next year,the difference of soil surface moisture at Mary that influence the speed of adult emergence,the difference whether have trees near citrus orchards 200 meter.,this paper success quantified the factor using multi-source remote sensing data and using GIS spatial analysis technical.According the investigate data of fruits injury citrus orchards percentage as prior knowledge,acquired the spatial distribution of Bactrocera minax(Enderlein) suitable area and non-suitable area In YIDU City,this new method is fitted for small size and multi-factor analyzing.更多还原
