摘要:

人地关系是地理学的永恒研究主题,也是助推可持续发展理念落实的关键科学问题。基于系统理论,运用系统动力学方法,探究人地关系的内在结构及要素关联,进而构建人地系统模型,模拟在基础模式和调控模式2种发展情景下至2050年中国人地关系的发展趋势及核心特征。结果表明:在以人口?经济?社会?资源?环境组成的现代人地系统中,存在4条核心的正负反馈回路,5类要素在系统中具有不同角色:人口是主因,经济是促因,资源是支撑,环境是表征,社会是调控。2017―2050年,若任由现今的人地相处模式延续下去,核心资源环境要素将始终处于高压状态,人地系统面临崩溃风险。而在承载多种政策意图的调控发展模式下,虽然核心资源要素依然有超载状态,但系统整体趋势向好,人地关系将迎来拐点期。未来相关政策调控还需持续在能源供需缺口及减排目标上多做努力。

Abstract:

Man-land relationship is the eternal research subject of geography and the key scientific issue to promote the implementation of sustainable development. Based on systematic thought, this paper applies system dynamic method that is good at dealing with complex interactive relations to explore the internal structure and element correlation of man-land relationships, and to construct man-land system model to simulate the development trend and core characteristics of China’s man-land relationship until the middle of this century under the two development scenarios, that is basic mode and regulatory mode. The results show that, in the contemporary man-land system composed of population, economy, society, resources and environment, there are four core positive and negative feedback loops, and the aforementioned five factors play different roles in the system, which can be summarized as: population is the main cause, economy is the promoting cause, resources are the foundation, environment is the representation, and society is the regulation. From 2017 to 2050, if the current man-land relationship mode is allowed to continue, the core resources and environmental factors will always be under high pressure, and the man-land system will face the risk of collapse. However, under the regulatory development mode bearing multiple policy intentions, although the core resource factors are still overloaded, the overall trend of the system is positive, and the man-land relationship will meet its inflection point. In the future, relevant policy regulation needs to continue to make more efforts in the gap between energy supply and demand, as well emission reduction targets.

Key words: man-land relationship, future trend, system dynamic, simulation, China
