摘要:

乡村振兴是支持我国农业经济高质量发展的重要战略,其中,种植业集聚是优化乡村发展布局、优化农业产业结构、推进农业发展的重要抓手。为促进种植业绿色高质量发展,文章利用基尼系数、区位熵、清单分析法,核算2007—2020年长江流域19省(市)的种植业集聚水平和农业面源污染排放量,分析二者的时空变化规律,利用空间杜宾模型和门槛模型检验二者之间的关系。研究结果表明:1)长江流域种植业集聚与农业面源污染时空分布及其变化特征相异,优势农产品区域集聚明显,且稳步提高,但各省市发展较不平衡;2)长江流域农业面源污染存在显著的空间正相关性,相对于地理距离,经济距离下种植业集聚更容易加剧农业面源污染,且具有显著的正向空间溢出效应,在影响当地环境的同时,对经济相关地区也产生影响;3)长江流域内种植业集聚对农业面源污染的影响存在门槛效应,随着农业经济发展水平的不断提高,种植业集聚对农业面源污染的加剧程度减弱;4)长江流域农村人口规模、农业经济水平、城镇化的发展加剧了农业面源污染,农业技术进步和财政支农力度则有效改善农业面源污染,环境规制的影响效果则不显著。对此,提出如下政策建议:优化种植业集聚的空间布局,提高种植业集聚质量;建立联动机制,加强区域间农业面源污染的协同治理;推动农业经济发展水平稳步提高,发挥种植业集聚对农业面源污染的减缓效应;合理利用财政资金,增强农业环境规制,促进种植业绿色化发展。

Abstract: Rural revival is a pivot strategy to support quality development of China ‘s agricultural economy, of which planting agglomeration is the key step in optimizing rural layout, increasing agricultural structure and pushing agricultural development. To booster a green quality development of planting, this paper uses Gini coefficient, locality entropy and listing to estimate 2007 to 2020 planting agglomeration levels and agricultural area pollution emission of 19 provinces/cities in Yangtze River stream, and to analyze their temporal-spatial changing rules which are tested by means of spatial Dubin model and threshold model. Planting agglomeration differs from temporal-spatial distribution and changes of agricultural area pollution, with dominant agricultural production of obviously regional agglomeration, and steadily rising, variable in provinces/cities. Its agricultural area pollution has outstandingly spatial positive correlation, easily worsened by economy distance more than by geographical distance. Its striking positive spatial overflowing impacts the local environment and economy as well. A threshold effect exists in the impacts of planting agglomeration on agricultural area pollution, diminishing with rising agricultural economy. Agricultural area pollution is aggravated by rural population scale, economy and urbanization in Yangtze River stream, but improved by agriculturally technical advances and financial supports, little impacted by environmental regulations. This paper presents suggestions on optimizing spatial pattern of planting agglomeration to increase its quality, enhancing regional collaboration in controlling agricultural area pollution, pushing agricultural economy to mitigate agricultural area pollution via planting agglomeration, and appropriately using governmental funds and intensifying agriculturally environmental regulations to promote green planting.

Key words:

Yangtze River Stream, planting agglomeration, agricultural area pollution, agricultural economic development; spatial effect, threshold effect
