基于自然适宜性的农业生产景观分区与调控——以湖南省长沙县金井镇为例

Zoning Control and Regulation of Agricultural Production Landscapes Based on Natural Suitability ——A Case Study of Jinjing Town of Changsha County in Hunan Province

农业生产景观自然适宜性研究是新农村建设中农业景观规划和土地整治的基础。本文在界定农业景观内涵和提取出农业生产景观类型的基础上,构建农业生产景观自然适宜性评价指标体系,利用GIS栅格技术与自然适宜性综合评价模型进行农业生产景观自然适宜性评价,将湖南省金井镇农业生产景观类型划分为高度适宜类、中度适宜类和低度适宜3个等级。在此基础上,将金井镇农业生产景观划分为粮菜生产区、经济园林生产区、农业生产限制区,进而提出其相应的发展调控模式。研究结果为区域农业生产景观规划和农业土地综合整治提供有力的技术手段和科学支撑。

The study on natural suitability of the agricultural production landscape is the basis of the agricultural landscape planning and the consolidation of rural residential area in new countryside construction. In this paper, with the definition of agricultural landscape and the extraction of agricultural production landscape types, the index system of suitability evaluation was built by considering the theory and methods of farmland. Taking Jinjing Town of Changsha County in Hunan Province as the study area, with the help of comprehensive evaluation model of natural suitability level and GIS technique, the study divided the town into highly suitable, moderate suitable and low suitable levels for the agricultural production landscapes, and food and vegetable production zone, economic landscape zone and restricted zone for agricultural production. Furthermore the comprehensive characteristics of the each zone were concluded and the corresponding regulation and control modes were suggested. The results could provide theoretical support and technical means for the agricultural landscape planning and comprehensive consolidation of agricultural land.
