摘要
研究目的:以流域为研究单元,从流域土地利用变化及其驱动力,流域土地利用模拟预测,流域景观格局变化及驱动力角度对已有的研究进行总结;而后将土地利用与景观格局改变对流域引发的生态环境影响进行理论总结与分析。研究方法:文献综述法。研究结果:在接下来的研究中应加强以下方面的研究工作:1加强对流域土地利用和景观格局变化驱动力对变化过程的累积效应研究;2强化对研究尺度与粒度探讨研究;3综合探讨土地利用与景观格局变化的关系及二者对流域的环境影响;4加强理论应用于实际的探索研究,优化流域土地合理利用与景观规划。
Research Objective: This paper selected river basins as research units,elucidated and summarized the previous research results from perspectives of land use change and its corresponding driving forces,simulation and estimation of land use changes,landscape pattern change and its corresponding driving forces and summarized environmental impacts caused by and use and landscape pattern changes systematically. Research method: Reviewing methodology; Research results: Some suggestions were put forward after recognizing shortages of the existed research results: First,strengthen researches on accumulation effects of driving forces influencing the change processes of land use and landscape patterns. Secondly,strengthen the exploration on researching scale and granularity in further related researches. Thirdly,probe the relationship between land use and landscape pattern and their compound environmental impacts on the river basin comprehensively. Finally,carry out researches on how to put theory into practice,optimize land use and landscape planning of river basins.
