北京市蔬菜专业村发展时空动态研究

蔬菜产业是关系国计民生的重要产业,产业化生产是实现蔬菜产业现代化的重要路径。本文以北京蔬菜专业村为研究对象,选取区位数据、种植规模以及发展数量三个方面进行探讨,采用对比分析法、核密度分析法,对北京市2008-2016年蔬菜专业村空间分布的动态变化特征进行分析。结果显示,北京市郊区蔬菜专业村数量呈现先增长后降低的趋势、在地理区位变化上由相对聚集向相对均匀分布变化、种植规模差异化程度逐渐降低等特点。研究建议加快培育蔬菜新品种、加强高端蔬菜产品生产；要延长蔬菜产业链,发展蔬菜全产业链服务平台建设；要抓住“互联网+”机遇,打造京郊蔬菜品牌化产品,推动蔬菜产业又快又好发展。

Spatial and temporal dynamics of vegetable village development in Beijing

Vegetable industry is an important industry related to national economy and people''s livelihood, and industrial production is an important path to realize the modernization of vegetable industry. This paper takes Beijing vegetable specialty village as the research object, selects location data, planting scale and development quantity to discuss, and uses comparative analysis method and nuclear density analysis method to analyze the dynamic characteristics of spatial distribution of Beijing vegetable specialty village from 2008 to 2016. The results showed that the number of specialized vegetable villages in the suburbs of Beijing showed a trend of increasing first and then decreasing, changing from relative aggregation to relatively uniform distribution in geographical location changes, and gradually decreasing the degree of differentiation in planting scale. The research suggests accelerating the cultivation of new vegetable varieties and strengthening the production of high-end vegetable products. To extend the vegetable industry chain and develop the construction of a service platform for the whole vegetable industry chain; We should seize the opportunity of " internet plus" to build brand-name vegetables products in the suburbs of Beijing so as to promote the rapid and sound development of the vegetable industry.
