摘要
借助GIS空间分析方法探索长江经济带3 321个森林乡村的空间分布特征和地域分异规律,并辅之缓冲区和叠置分析、地理探测器模型探究森林乡村空间分布的主要影响因素.结果表明:长江经济带森林乡村空间分布呈现典型的集聚特征,上游地区分布多、下游地区分布少,核密度分布整体上呈"双核心—单核点—环核群"分布态势;长江经济带森林乡村空间分布具有显著的空间正相关性,表现为东热西冷、冷热交替的空间分异格局;长江经济带森林乡村空间分布格局受自然地理环境、生态环境质量、社会发展状况、经济发展水平的共同影响,其中耕地面积、常住人口、森林覆盖率是森林乡村空间分布的主要影响因子,其空间分异是影响因子共同驱动的结果.
Abstract
Using GIS spatial analysis methods to explore the spatial distribution characteristics and regional differentiation patterns of 3 321 forest villages in the Yangtze River Economic Belt,supplemented by buffer zone and overlay analysis,and geographic detector models to investi-gate the main influencing factors of forest-rural spatial distribution.The results showed that the spatial distribution of forest-rural areas in the Yangtze River Economic Belt presented typical agglomeration characteristics.The forest-rural areas were concentrated in the middle and upper reaches of the Yangtze River,followed by the distribution density in the lower reaches.On the whole,the distribution of nuclear density in for-est-rural areas presented a"double core-single point-ring core group"distribution.The spatial distribution of forest-rural areas in the Yan-gtze River Economic Belt had a significant spatial positive correlation,manifested as a spatial differentiation pattern of east hot and west cold,and alternating cold and hot.The spatial distribution pattern of forest-rural areas in the Yangtze River Economic Belt was jointly influenced by natural geographical environment,ecological environment quality,social development status and economic development level.Among them,cul-tivated land area,permanent population and forest coverage were the main influencing factors of forest-rural spatial distribution,and their spatial differentiation was the result of the joint driving of influencing factors.
