近10年临沂市LUCC及驱动力分析

LUCC of LinYi City and its Driving Force in Recent Decade

以山东省临沂市1990～2003年间土地利用类型动态变化为例，分析了变化过程及其驱动因素。研究表明：临沂市土地利用表现为城市工矿建设用地、交通用地急剧增加，未利用土地、耕地、林地、园地等大量减少；土地利用／土地覆被不够合理，土地利用程度综合指数较高；虽然城市工矿建设用地的动态度指数在下降，侵占其他土地类型的程度在减缓，但形势仍很严峻。最后指出城市化和工业化、经济发展、人口增长、政治经济政策是土地利用／土地覆被变化的主要驱动力。

The example of Lin Yi city land use and land cover in 1990 - 2003 has been brought forward. The process of change and driving factor were analyzed. We can included that the urban land and the transport land are increasing, while no - use land, plantation, forest, garden land are decreasing greatly. Finally the driving factors such as industrialization, urbanization, economy and policy were brought out.
