【摘要】 加拿大一枝黄花(Solidago canadensis L.)是一种的世界性的入侵性外来杂草。本文利用地理信息系统(GIS)的先进技术手段,针对2005年合肥地区一枝黄花的空间分布状况,进行空间分析研究表明,一枝黄花主要发生面积中,地质类型为第4纪Q3亚粘土、亚砂土,占发生面积的99.89%;地貌类型为缓低岗占发生面积99.89%;土壤亚类为潴育型水稻土占94.04%;土地利用方式为城镇用地占发生面积的60.67%。这些结果可为实现合肥基于GIS一枝黄花监测防治提供科学依据。更多还原

【Abstract】 Canada goldenrod(Solidago Canadensis L.) is a kind of alien invasive species.Solidago Canadensis has broken out in some district of Hefei.In this paper,as to the spatial distribution of the Solidago Canadensis in Hefei in 2005,we carry out the study of the spatial analysis.The area of Solidago Canadensis in Hefei have showed that Quaternary Period Q3 inferior clay and inferior sand(geological type) is 99.89%;the slow hillock(ground form type) 99.89%;Waterlogged paddy soil(soil type) 94.04%;land used of city and town(land-use type) is 60.67%.These results can offer the scientific basis for realizing the monitoring and preventing Solidago Canadensis in Hefei on GIS.更多还原
