摘要
自20世纪50年代以来,鄱阳湖区土地资源利用经历了“土地围垦—土地退化、生态破坏—土地整治、生态建设”发展变迁。利用RS、GIS技术研究证明,目前整个区域土地退化面积533 180 hm2,约占区域总面积的20%。分析鄱阳湖区土地资源利用的变化情况和土地退化的驱动力,主要是受鄱阳湖区自然资源条件及其相关土地政策实施、社会经济状况和农民土地利用观念的影响,其中降水因素、耕地缺乏、城镇用地扩张、区域性贫穷的影响尤为突出。结合土地整治、生态修复、生态乡村建设、土地政策等理念,提出了具有针对性的土地退化防治模式,为湖区土地可持续利用和土地退化防治提供参考。
Since 1950s,the land resources utilization of Poyang lake area has experienced development and variation of 'land reclamation—land deterioration,ecological destruction—land renovation,ecological construction'.The research by RS,GIS technology demonstrates that the land deterioration area in the whole region at present is 533180 hm^2,accounting for 20% of the total area.The variation of land resources utilization and driving power of land deterioration of Poyang lake are mainly influenced with natural condition and relative policy execution,social and economic condition and land utilization idea of peasants,in which,the influence of precipitation,farm land deficiency,city and town land utilization expansion,regional poverty are mostly prominent.Combined with ideas of land renovation,ecological restoration,ecological countryside construction,land policy etc.,the control mode directed against land deterioration is suggested,providing reference for sustainable utilization and deterioration control of land in the lake area.
