Analysis of land use change and its driving force in the Longitudinal Range-Gorge Region

关于陆地使用度，陆地使用变化率以及各种各样的陆地使用的地区性的差别的研究录入西南纵的范围峡区域(LRGR ) 被执行了在上地区性并且县规模。从社会经济的看法，我们也在研究区域分析了陆地使用变化的开车机制和各种各样的驱动力的相应空间范围。研究结果显示在地区性的规模上，农田，森林和草地在 LRGR，和草地严厉地衰退的陆地使用表演的结构的变化填写陆地使用的主要身体，农田增加和森林保持稳定。在县规模上，陆地使用被那陆地使用水平描绘是相对低的，并且陆地使用度，全面变化率和相对变化在不同陆地使用类型之中评价仍然存在。由分析，在 LRGR 的陆地使用变化被投资主要驾驶人力和物理资源，社会经济产量水平，自然灾难骚乱的紧张和工人的教育水平的紧张。然而， regionalism 在不同驱动力类型的影响范围存在。

The research on land use degree, land use change rate as well as regional difference of various land use types in the southwest Longitudinal Range-Gorge Region （LRGR） has been carried out on the regional and county scales. From the view of social economy, we have also analyzed the driving mechanism of land use change and the corresponding spatial scopes of various driving forces in the research area. The research result indicates that, on the regional scale, farmland, forest and grassland compose the main body of land use in the LRGR, and the structural change of land use shows that grassland declines sharply, farmland increases and forest keeps stable. On the county scale, the land use is characterized by that land use level is relatively low, and the land use degree, the comprehensive variation rate and the relative variation rate among different land use types still exist. By analysis, the land use changes in the LRGR are mainly driven by investment intensity of manpower and physical resources, the social economic output level, the intensity of natural disasters disturbance and educa- tional level of workers. However, the regionalism exists in the influence scope of different driving force types.
