沟域经济是山区发展的新视角,以密云县沟域数据为基础,针对沟域土地对经济发展、粮食供给和生态保护所能提供的支撑能力,构建了土地支撑能力定量评价方法,评价了各沟域的土地支撑能力,并与发展需求进行了比较,进而从沟域发展的经验事实中总结出面对土地支撑能力不足的响应途径。结果表明:土地支撑能力在空间上具有明显的非均衡性,各个沟域差异较大,整体存在土地的支撑能力不足,但通过发展沟域经济、优化响应途径,土地支撑能力和发展需求的差距逐步缩小,即土地相对支撑能力逐步得到提升和加强。
Ditch area economy is a new perspective of mountain development. Based on the data of ditch area in Miyun County, a quantitative evaluation method of land supporting capacity is constructed based on the supporting ability that the area can provide for economic development, food supply and ecological protection. The land support ability of each valley is compared with the development demand, and then the response to the shortage of land support capacity is summarized from the empirical facts of the development of the valley. The results show that: the land supporting capacity is obviously non-equilibrium in space, and there is great difference in each of the ditch land areas and the lack of supporting capacity of the whole land. However, through the development of ditch economy and optimization of response path, the gap between land supporting capacity and development demand Gradually narrowing, that is, the relative support of land has gradually been enhanced and strengthened.
