摘要:

［目的］通过对武都区境内耕地进行花椒种植适宜性评价，将区内花椒产业发展划分为高度适宜区、适宜区、勉强适宜区和不适宜区等4个差异区域，并从适宜区土壤属性、区划结果布局、适宜区和不适宜区界定、新技术推广使用和农村电商发展5个方面给出花椒产业发展壮大的建议。［方法］用行政区划图、土壤图和土地利用现状图叠加求交得到5 590个区划单元，利用模糊评价法和特尔斐法对选取的评价指标建立隶属函数模型和层次分析模型，通过县域耕地资源管理信息系统计算各区划单元综合得分。［结果］通过综合得分把区内5 590单元划分为高度适宜、适宜、勉强适宜和不适宜4个等级，并获取了各等级的分布位置和面积。［结论］对花椒产业发展影响程度从大到小依次为：海拔高度、有效土层厚度、坡向、年降雨量、有机质、质地、≥10℃积温和有效磷； 并根据此结果给出花椒产业扶贫区划的几点建议。

Abstract:

Based on the evaluation of planting suitability of pepper cultivation in the in Wudu District, the development of the pepper industry was divided into four different regions: highly suitable region, suitable region, reluctantly suitable region and unsuitable region. Some suggestions on the development of pepper industry were put forward from five aspects including the soil properties, zoning layout, definition of suitable area and unsuitable area, promotion of new technology and development of rural e commerce. 5 590 zoning units were obtained by overlapping the administrative division map, soil map and land use status map. The membership function model and analytic hierarchy model were established by using fuzzy evaluation method and Delphi method. The comprehensive scores of each zoning unit were calculated by county farmland resource management information system. According to the comprehensive score, 5,590 units in the area were divided into four grades: highly suitable region, suitable region, reluctantly suitable region and unsuitable region, and the spatial distribution location and area of each grade were obtained. The influence degree of pepper industry development from high to small was: altitude, effective soil layer thickness, slope aspect, annual rainfall, organic matter, texture, accumulated temperature ≥10℃ and available phosphorus, and some suggestions on poverty alleviation zoning of pepper were given according to the results.
