摘要
以陕西省商洛市为例,借助灰色线性规划模型,对宏观的土地利用结构优化进行了情景设定与分析。研究结果表明,在未来10 a内,商洛市土地利用结构仍以农用地为主,适宜发展以林为主,林农结合的复合经营方式,建立立体复合生态系统,保护湿地,防止水土流失;在土地利用结构优化过程中,要充分考虑区域发展的整体效益和长远利益,注重经济效益、社会效益和生态效益的协调统一。研究表明,情景分析在土地利用结构优化中具有可行性,在宏观市域尺度上的土地利用结构优化配置中具有有效性。
As a case study,the grey linear programming method has been used to analyze the land use structure optimization in Shangluo City in Shaanxi Province.It shows that farmland will still be the main land use type in the next 10 years in this area.The multiple-purposed land use and forestry mixed with cultivation should be promoted,considering multidimensional ecosystem construction and soil,water and wetland conservation.In the process of land use structure optimization,the economic,social and ecological effects of the land use should be emphasized comprehensively with the guarantee of long-term benefits and sustainable development of this area.Scenario analysis method is proved to be a feasible and effective method in land use structure optimization.
