摘要/Abstract

摘要：

以长株潭地区23个县市区为研究区域,分别从农产品供给功能、就业和社会保障功能、生态保育功能、文化传承和休闲功能构建评价指标体系,综合运用熵值法、多指标综合评价法和农业功能变化的时空差异诊断模型等方法对长株潭地区1998~2014年农业功能的时空动态变化特征进行研究,根据各地区功能特征提出农业功能发展调控策略。研究结果表明：① 长株潭地区农产品供给功能有大幅提升,其重心有向外进一步扩散趋势;长株潭地区核心区域劳动力就业与社会保障功能下降幅度较大;大围山、罗霄山脉等山地丘陵区生态保育功能优势进一步凸显;文化传承和休闲功能部分区域获得进一步发展,但空间变化差异较小。② 研究发现不同区域农业主导功能不同,根据各地区农业功能不同优势特征,结合自身特色因地制宜发展优势农业并提出相应的优化调控对策,从而为长株潭地区农业多功能发展与功能特征的识别及确定提供理论依据。

Abstract:

Agriculture, rural areas and farmers have always been the fundamental issues concerning the national economy and people’s livelihood. China’s heavy investment in urban areas for a long time aimed solely at economic development at the expense of agriculture, thereby lead to a huge gap between urban and rural areas. In order to bridge the gap between urban and rural areas in China, development of the countryside is the priority. Therefore, taking agriculture as the starting point and driving force for rural development can promote rural economic development and sustainable agricultural development. At present the structure and type of rural agricultural functions have gradually begun to upgrade, evolving from the traditional, single function to multi-functional. Therefore domestic and foreign scholars have gradually increased their research on multi-functions in agriculture, mainly focusing on the evaluation and division. But, there is lack of research on the spatio-temporal dynamics, in particular, on the regulatory pathways for the evolution of agricultural functions. Based on the data from land use detailed surveys in the Changsha-Zhuzhou-Xiangtan urban agglomerations from 1998 to 2014, the study analyzed the spatio-temporal dynamics of agricultural function by agricultural regional multi-function index and regional agricultural function spatio-temporal differences identifying model. And it covers four aspects: the agricultural products supplying function, the labor employment and social security function, the ecological conservation function, and the cultural heritage and recreational function. The results showed that the agricultural products supplying function was enhanced and its core has the tendency to spread. The labor employment and social security function weakened to a large extent. The ecological conservation function in hilly area also enhanced. The cultural heritage and recreational function gained prominence in the urban areas.The study found that different regions have different dominant functions of agriculture, based on the characteristics and advantages of agricultural functions in different regions. Combining with the characteristics,we should develop superior agriculture functions suitable for local conditions and put forward corresponding optimization and control measures, thus providing a theoretical basis for identification and determination of multi-functional agriculture development and functional characteristics in Changsha-Zhuzhou-Xiangtan urban agglomerations.

Key words: agricultural function, spatio-temporal change, coordinated development, Changsha-Zhuzhou-Xiangtan Urban Agglomerations
