摘要:
[目的]探究华北农牧交错区土地利用/覆被变化(LUCC)对区域生态环境的影响,为类似地区国土空间用途管制和生态文明建设提供理论参考。[方法]基于华北典型农牧交错区内蒙古多伦县2004年、2009年和2014年3期土地利用现状数据及其变更调查资料,获取该区2004-2014年LUCC时空数据。参考Costanza和谢高地等的研究成果,选取生态系统服务价值、生态环境质量指数和LUCC生态贡献率等,构建LUCC与生态环境质量评价体系。[结果]①2004-2014年,研究区土地利用/覆被类型发生明显改变。②生态系统服务价值总量不断提高,主要由林地增加而来;草地、耕地、水域和未利用地生态服务价值的减少在一定程度上削弱了这种增加趋势;10 a来研究区各土地利用/覆被类型生态系统服务价值变化与各自面积变化规律一致。③从生态环境质量指数变化来看,区域生态环境质量不断改善。但从变化细节上分析,生态环境存在改善和恶化双向变动;草地转向耕地和建设用地是该区生态环境恶化的主导因素,未利用地向草地和林地转换则促进生态环境质量的改善。[结论]生态文明建设过程中要切实重视生态脆弱区土地利用变化对区域生态环境之影响;从提高土地利用效率,加强"山水田林湖草"生命共同体建设,构建合理的国土空间规划体系入手,引导区域人口、经济、资源和环境持续高质量发展。

Abstract:
[Objective] The impacts of land use/cover change(LUCC) on the regional ecological environment in agro-pastoral transitional zone in Northern China were studied in order to provide a theoretical reference for future land use in similar areas.[Methods] Based on the changing survey information and land use data of Duolun County, Inner Mongolia Autonomous Region in 2004, 2009 and 2014, the spatio-temporal data from 2004 to 2014 was obtained. And consulting the research results of Costanza and Gao et al, the ecosystem service values, ecological environment quality index and the contribution proportions of land use/cover types were selected, to build the assessment system between LUCC and ecological environment qualty.[Results] ① The land use/cover types had obviously changed in 2004-2014. ② The total value of ecosystem services kept improving and mainly came from woodland. While the reduction of ecological service values of grassland, farmland, water area and unused land weakened the increasing trend in some extent, the change rules of ecosystem service values were similar to area changes respectively. ③ From the point of ecological environment quality index changes, the ecological environment quality of this study area improved. But from the change details, this change had two-way driving mechanism. Grassland transferred to farmland and construction land was the dominant factor of degradation of the ecological environment, while the unused land transferred to grassland and woodland promoted the improvement of the ecological environment quality.[Conclusion] In the process of ecological civilization construction, it should attach great importance to the impact of land use change on regional ecological environment in ecologically fragile areas, and guide the sustainable and high-quality development of regional population, economy, resources and environment by improving the efficiency of land use, strengthening the construction of "mountain, paddy field, forest, lake and grass" life community and building a reasonable land and space planning system.
