为了更好地完善区域土地利用结构,促进土地资源可持续利用,利用遥感和GIS技术,提取了1995年和2006年青海省刚察县土地覆被变化情况。通过引入土地利用变化指数模型、转移矩阵模型及转化倾向性模型,分析了该区域土地利用变化的时空特征,并对其驱动力进行了初步探讨。结果表明：11年间刚察县土地利用处于稳定发展时期,受政策、经济等人为因素的影响,并考虑了自然因素的限制,其利用方式逐渐走向生态、集约;通过挖掘土地类型间的转化倾向,寻求土地利用变化驱动力,更好地阐明了土地景观空间发展的内在规律,为土地资源的可持续利用提供了有效的决策支持。

In order to improve regional land use structure and promote the sustainable land use development in a more profound way, information has been extracted of land use and land cover from 1995 to 2006 in Gangcha County, Qinghai Province, applying remote sensing and GIS technology. Using such models as landscape index, land use transfer matrix, and conversion tendency of land use, this paper analyzes the change of landscape in spatial and temporal dimensions as well as the driving force. The results show that land use of Gangcha County has been in a stable phase of development towards a pattern of ecological and intensive use, influenced by policy, economy and other human factors and limited by natural factors. Through exploring the tendency of transformation among different land types and seeking the driving force of land use change, the paper clarifies the inherent law of land landscape space development in Gangcha County, providing effective support for sustainable use of land resources.
