【摘要】 对河北省土地利用/覆被变化的动态变化特征、空间分布特征和景观格局变化进行研究,结果表明:河北省土地覆被类型以耕地和林地为主,并具有明显的地域差异和垂直空间分布差异;土地利用程度综合指数逐年提高,2000~2005年土地利用程度变化量和变化率均低于1987~2000年;2000~2005年时段综合土地利用动态度是1987~2000年时段的1.19倍;土地利用/覆被变化的景观多样性指数逐渐增加,均匀度指数呈增加趋势,优势度指数总体数值较大,并呈减少趋势。更多还原

【Abstract】 The purpose of this paper is to analyze the dynamic change character,distribution character and landscape pattern change. The results show Cultivated land and woodland are the main types of land cover, and they have distinct zone difference and vertical distribution difference. land use integrated index increases year by year, The variation value and variation rate during year 2000 to 2005 is lower than year during 1987 to 2000. the integrated land use dynamic degree is 1.19 times of that during 1987~ 2000. The landscape diversity index and landscape evenness index were increasing, landscape dominance index was large in numerical value and showed a decreasing trend.更多还原
