摘要:

目的 构建乡村振兴基础条件综合评价体系，明确不同分区乡村振兴的优势条件和不足条件，分类提出乡村振兴的建议。方法 文章基于数据可获取性及科学性等原则选择乡村主体、资源禀赋、产业基础、区位条件和自然环境等5个评价指标，运用熵权法确定指标权重，利用综合评价法计算2018年天水市乡村振兴基础条件综合得分，采用自组织映射法（SOM）以乡（镇）为单元进行分区，并根据不同评价因子得分明确各区发展基础的优势与短板。结果 （1）天水市乡村振兴基础条件有较大的差异性，综合条件较高和较差乡（镇）占比较少，基础条件一般的乡（镇）数量占比最大，各乡（镇）各评价指标具有较大的空间分异性；（2）天水市乡村振兴基础条件可以分为4个区，综合得分分别为0.009 4、0.007 7、0.006 2和0.004 6，4个分区结果的优势条件分别是产业基础、资源禀赋、资源禀赋、乡村主体，而其不足条件分别是资源禀赋、乡村主体、自然条件和产业基础。结论 天水市各乡（镇）乡村振兴的基础条件具有明显的空间差异性，乡村振兴战略实施应依托优并发挥优势条件，补齐短板，因地制宜推进。

Abstract:

The comprehensive evaluation system for the basic conditions of rural revitalization is constructed, the advantages and disadvantages of rural revitalization in different districts are defined, and the suggestions for rural revitalization are put forward. Based on the data availability and the scientific principles of choice of rural subjects, resources endowment and industrial foundation, location conditions and five evaluation indexes such as natural environment, using the entropy weight method to determine index weight, and use of comprehensive evaluation method to calculate comprehensive score of 2018, tianshui rural revitalization of basic conditions, by using the self-organizing mapping (SOM) with township (town) as a unit partition, according to different evaluation factor score partition clear advantage and short of district development foundation. The research results show that: (1) The basic conditions for rural revitalization in Tianshui City are quite different. Townships (towns) with higher and lower comprehensive conditions account for a relatively small proportion. Townships (towns) with general basic conditions account for the largest proportion, and each township (town) has its own proportion. The evaluation indicators have large spatial differentiation. (2) The basic conditions for rural revitalization in Tianshui City can be divided into 4 districts, with comprehensive scores of 0.009 4, 0.007 7, 0.006 2 and 0.004 6, and the advantages of the 4 districts are respectively. It is the industrial foundation, resource endowment, resource endowment, and rural main body. Therefore, the insufficient conditions are resource endowment, rural main body, natural condition and industrial base. The basic conditions for rural revitalization in each township (town) of Tianshui city have obvious spatial differences. The implementation of the rural revitalization strategy should rely on the best and give play to the advantages, make up for the shortcomings, and proceed in accordance with local conditions.
