安徽省农业绿色发展水平时空演变特征及障碍因子诊断

Temporal and Spatial Evolution Characteristics and Obstacle Factor Diagnosis of Agricultural Green Development Level in Anhui Province

  • 摘要: 文章从资源节约保育、产出质量高效、生态环境安全三个维度构建农业绿色发展水平评价指标体系,运用熵权-TOPSIS、障碍因子诊断模型和空间自相关模型,对安徽省农业绿色发展情况进行实证分析。结果表明:(1)2017—2022年安徽省农业绿色发展水平总体呈稳步上升态势,其中,资源节约保育分波动上升,产出质量安全分稳定提升,生态环境安全分快速增长。从区域发展水平来看,皖南地区发展最好、皖中次之、皖北地区发展最差。(2)2022年安徽省农业绿色发展水平高值区主要集中在皖南、皖中地区,低值区主要集中在皖北地区,呈现“南高北低、东高西低”的空间分布特征。各市的农业绿色发展水平展现了一定高值和低值集聚特征。(3)障碍度分析表明制约皖北地区农业绿色发展的主要因素为农业劳动生产率、农村常住居民人均可支配收入及单位面积农业产值;而对皖南、皖中来说,则为单位面积农业产值、节水灌溉面积和农村常住居民恩格尔系数。为此,安徽各地区应结合自身短板,因地制宜、精准施策,合力推动安徽省农业高质量绿色发展。

     

    Abstract: This article built an evaluation index system for agricultural green development from three dimensions of resource saving conservation, high-efficiency output quality, and ecological environment safety. Using entropy weight -TOPSIS, obstacle factor diagnosis model and spatial autocorrelation model, the green agricultural development in Anhui Province was empirically analyzed. The research results showed that, (1) From 2017 to 2022, the level of agricultural green development in Anhui Province had generally risen steadily. Among them, resource saving conservation points fluctuations had increased, output quality and safety were steadily increased, and the safety of ecological environment security had grown rapidly. From the perspective of regional development, the development of southern Anhui was the best, followed by Central Anhui, and the development of northern Anhui was the worst. (2) In 2022, the overall spatial distribution of agricultural green development in Anhui Province was mainly concentrated in southern and central Anhui, and the low value areas were mainly concentrated in northern Anhui, showing the spatial distribution characteristics of “high in south and low in north, high in east and low in west” . The level of agricultural green development in each city showed a certain high and low -value agglomeration characteristics. (3) Analysis of obstacles indicating that the main factors that restrict the green development of agricultural development in northern Anhui were agricultural labor productivity, per capita disposable income of rural residents, and agricultural output valued for unit area; for southern Anhui and Central Anhui, agricultural output valued for unit area,water-saving irrigation area and engel coefficient of permanent residents in rural areas were the main factors.All regions of Anhui should combine their own shortcomings, adapt to local conditions and accurate policies, and jointly promote the high -quality green development of Anhui Province.
