摘  要:
辽中地区矿业城市是我国重要的能源生产和重工业基地,研究其土地利用变化有利于改善环境质量,提高土地利用效率。分析了1985—2000年鞍山、抚顺、本溪土地利用变化指数、土地利用变化程度综合指数、土地利用结构信息熵、土地利用景观指数及其驱动力。结果表明:辽中地区矿业城市土地利用变化整体上呈现耕地、建设用地增加,林地、草地减少的趋势;不同矿业城市变化率最大的土地类型均不相同,鞍山为建设用地,增加5.45%;抚顺为水域,增加3.19%;本溪为草地,减少7.29%。土地利用程度变化综合指数均为正值,且鞍山>本溪>抚顺;土地利用结构信息熵均呈增长趋势,2000年鞍山为0.603,抚顺为0.406,本溪为0.407;景观破碎化程度加大,破碎度为鞍山>本溪>抚顺,景观多样性指数较高,景观结构复杂,景观多样性和均匀性均为鞍山>抚顺>本溪;自然条件的差异是土地利用变化差异的基础,人类社会经济活动和政策法规是土地利用变化的主要驱动力。

摘  要:
The mining cities in Central Liaoning are the important bases of energy production and heavy industry in China. It’s of significance to investigate their land use change, which would benefit to the improvement of environment quality and land use efficiency. This paper analyzed the land use change in Anshan, Fushun and Benxi from 1985 to 2000, and the results showed that on the whole, the land area for agricultural production and municipal construction increased, while forestland and grassland decreased. The land use type with maximal change differed with the cities. In Anshan, the land for municipal construction increased by 5.45%; in Fushun, water area increased by 3.19%; and in Benxi, grassland decreased by 7.29%. The integrated index of land use change degree in the three cities were all positive, and followed the sequence of Anshan>Fushun>Benxi. Land use structure information entropy had an increasing trend, and its value in 2000 was 0.603 for Anshan, 0.406 for Fushun, and 0.407 for Benxi. The landscape fragmental degree was enlarged, which followed the order of Anshan>Benxi>Fushun, and the landscape structure was complex, with higher landscape diversity index and followed the sequence of Anshan>Fushun>Benxi. Natural condition was the determinant factor of the difference in land use, whereas human activity and policy were the main driving factors of land use change.
