Study on the driving forces of land use/cover temporal-spatial change. On the basis of the systematical study on natural and social-ecomic factors including climate, population, technology and affluence status etc. during the past 50 years in this area, the multivariate statistics simulation models of LUCC were developed for two periods of 1950's-1980's and 1986-2000 respectively. Then, the Thiesson polygon method was used to the spatial allocation of soci-economic factors, thereby the spatial relationship between land use degree change and socieconomic factor variation was detected within GIS. Based on the analysis of the integrative characters in different geographical divisions, the electivity index was employed to describe the possible impacts of the natural landscape structure on spatial differentiation of land use transition. At last, correlation analysis between major roads and the distribution of land use change was made.

分析近50年气候资料和人文因子在不同年代的变化特点，系统地研究了气温和降水等自然因子和人口、农牧业发展、经济状况等人文因子对区域土地利用变化的影响；从时间序列的角度分析了50年代至80年代初和80年代中期至2000年两个时段土地利用／土地覆被变化的驱动因子，在相关分析的基础上，分时段建立了区域土地利用／覆被变化的自然-人文影响统计诊断模型；针对不同经济类型区选择典型县，分析近15年土地利用变化外在人文驱动力的区域相似性和差异性；尝试以THIESSEN多边形方法进行社会经济统计数据的空间化处理，探讨了土地利用程度变化与人文因素变化的空间相关关系；以优先指数模型和土地利用类型转化率与距交通干线距离的相关模型分析了景观自然与人文结构对土地利用空间转化过程的影响。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
