摘要
运用1996～2003年土地利用数据,对新乡市土地利用动态变化和驱动力进行了深入分析。结果表明：8年来新乡市建设用地显著增加,耕地、水域面积明显减少;土地利用结构仍以农业用地为主,但各地类间转换激烈;耕地质量总体上呈下降趋势;采用逐步回归分析方法,得出城市化水平和人均GDP是影响新乡市常用耕地变化的主要驱动因子;土地数量结构多样性指数和综合程度指数均呈显著增长态势,表明新乡市土地利用结构趋于合理,土地利用强度明显增强。
Land use change can reflect the influence of human activity on nature, Based on the land use statistic datum in 1996- 2003, this article deeply analyzed the dynamic change on land use and its driving forces in Xinxiang city. The results show that constructive lands are increased, while the cultivated land and water field are decreased greatly; Between each kind of land type converse violently, farmland is the main type of land use; land quality＇s change trends decrease; the major human driving forces of cultivated land change are urbanization and per capital of GDP by Stepwise Regression Analysis. Some countermeasures are proposed to realize sustainable utilization of land in Xinxiang city.
