摘要
根据刺梨的生长条件,选取年平均气温、年平均降雨量、坡度、坡向和土层厚度作为六盘水市刺梨种植适宜性的评价指标,采用层次分析法确定各指标权重,根据刺梨种植条件综合区划建立评估模型,融合GIS技术进行六盘水市刺梨种植适宜性区划。结果表明,六盘水市刺梨种植高适宜区,主要分布于盘州市的东北及东南部,面积占六盘水市总面积的10%;较高适宜区,分布于水城县(水城区)中南部,占总面积9%;一般适宜区,分布于盘州市的南部、中西部及六枝特区东南部,占总面积36%;基本适宜区,大面积分布于水城县,占总面积43%;不适宜区,分布于水城县西北部、钟山区西部,占总面积2%。
According to the growth conditions of Rosa roxburghii,the annual average temperature,annual average rainfall,slope,slope aspect and soil thickness were selected as the evaluation indexes of planting suitability of Rosa roxburghii in Liupanshui City.The weight of each index was determined by analytic hierarchy process(AHP).According to the comprehensive regionalization of Rosa roxburghii planting conditions,the evaluation model was established,and the planting suitability zoning of Rosa roxburghii in Liupanshui City was carried out by combining GIS technology.The results show that:the high suitable area for planting Rosa roxburghii in Liupanshui City,mainly distributed in the northeast and southeast of Panzhou City,accounting for 10%of the total area of Liupanshui City;higher suitable area,distributed in the central and southern part of Shuicheng District,accounting for 9%of the total area;general suitable area,distributed in the south,central and west of Panzhou City and southeast of Liuzhi Special Economic Zone,accounting for 36%of the total area;basic suitable area,a large area is distributed in Shuicheng District,accounting for 43%of the total area;and unsuitable area,distributed in the northwest of Shuicheng District and the west of Zhongshan District,accounting for 2%of the total area.
