摘要: 利用新疆沙湾县及周边15个气象站点1961—2018年气候资料和地理信息数据,通过ArcGIS软件、回归分析和模糊数学等方法对7月平均气温、≥15 ℃积温、4—5月最低气温≤0 ℃天数、6—8月最高气温≥35 ℃天数等指标因子构建模糊隶属度函数,综合考虑气候条件和地理因素,将气候资源分布图与灾害风险等级图进行重分类,分为1、2、3、4共4个等级,进行模糊叠加,将沙湾县辣椒种植区域分为最适宜区、适宜区、次适宜区和不适宜区。结果表明,沙湾县辣椒最适宜种植区主要分布在沙湾县铁路和乌奎高速公路两侧;适宜区在乌奎高速公路以南少部分区域和中部偏北大部分地区;次适宜种植区主要分布在北部地区和南部狭长区域;不适宜种植区主要分布在北部沙漠地区、南部低山和中高山区域,该区不适宜大面积发展辣椒生产,应选取耐寒品种,以提高种植效率。

Abstract: Based on the climate data and geographic information data of Shawan county and its surrounding 15 meteorological stations from 1961 to 2018, ArcGIS software, regression analysis and fuzzy mathematics were used to construct fuzzy membership function for index factors such as the average temperature in July, ≥15 ℃ accumulated temperature, the days of minimum temperature ≤0 ℃ from April to May, and the days of maximum temperature ≥35 ℃ from June to August. Taking climate conditions and geographical factors into consideration, the climate resource distribution map and disaster risk level map were reclassified into four levels, namely 1, 2, 3 and 4, and fuzzy superposition was carried out to divide the pepper planting area in Shawan county into the most suitable area, the suitable area, the sub-suitable area and the unsuitable area. The results showed that the most suitable planting areas of pepper in Shawan county were mainly located on both sides of Shawan county railway and Wukui expressway; The suitable areas were in a few areas south of Wukui expressway and most areas north of central part; The sub suitable planting areas were mainly distributed in northern and southern narrow and long areas; The unsuitable planting areas were mainly distributed in northern desert area, southern low mountain and mid high mountain area, in order to improve the planting efficiency, cold tolerant varieties should be selected.
