基于GIS的四川省引扩种苍溪雪梨适宜性评价研究
|
摘要
以苍溪雪梨为例,利用遥感(RS)和地理信息系统(GIS)技术,采用层次分析法(AHP)和空间分析法,结合苍溪雪梨生长发育适宜的气候、地形等生态环境因子,研究了苍溪雪梨在四川省的适宜性分布范围,对其适宜性分布进行评价,以期为苍溪雪梨在四川省的适宜性种植结构调整提供参考。结果表明:通过遥感与GIS技术分析所得适宜性结果与苍溪雪梨资源实际分布范围基本吻合。四川省扩引种苍溪雪梨的总适宜面积为11.98万km~2,占四川省总面积的24.87%。其中最适宜性面积0.69万km~2,占四川省总面积的1.43%;较适宜性面积2.84万km~2,占四川省总面积的5.89%;适宜区约有8.46万km~2,占四川省总面积的17.56%。
Taking Cangxi Snow pear as an example,using remote sensing(RS)and geographic information system(GIS)technology,analytic hierarchy process(AHP)and spatial analysis method,combined with the suitable climate,topography and other ecological environment factors of Cangxi Snow pear,the suitability distribution range of Cangxi Snow pear in Sichuan Province was studied,and its suitability distribution was evaluated in order to provide a reference for the adjustment of suitable planting structure of Cangxi Snow pear in Sichuan Province.The results showed that the suitability analysis by remote sensing and GIS technology was basically consistent with the actual distribution range of Cangxi Snow pear resources.The total suitable area for the expansion of Cangxi Snow pear in Sichuan was 119 800km~2,accounting for 24.87% of Sichuan′s total area.Among them,the optimum area was 6 900km~2,which accounted for 1.43%of the total area,the more suitable area was 28 400km~2,accounting for 5.89% of the total area,and the suitable area was about 84 600km~2,accounting for17.56% of the total area of Sichuan Province.
