【摘要】：随着社会发展,人类对土地的需求不断增加,土地的过度开垦和不合理使用使有限的土地资源不断恶化,土地资源的生态性能和可持续利用能力下降。然而,土地是人类赖以生存的物质基础,土地资源恶化严重影响着人类的可持续发展。因此,加强土地资源管理、改善土地资源状况刻不容缓,进行土地资源可持续利用方面的研究是非常必要的。本文首先对生态足迹理论和能值理论进行梳理,在此基础上,从土地资源的能值来源和利用角度出发,构建土地资源能值—生态足迹模型。然后利用该模型计算土地资源的生态承载力和生态足迹,用人均生态赤字/盈余、可持续发展指数、生态足迹多样性指数和万元GDP生态足迹综合分析土地资源可持续利用情况。最后,以山西省为例进行实证研究:分析了山西省2000-2012年土地资源可持续利用情况;通过ArcGIS分析了山西省各地市土地资源可持续利用的空间差异;利用灰色预测模型对山西省2013-2022年土地资源可持续利用情况进行预测。通过研究,得出如下结论:(1)山西省2000-2012年土地资源人均生态承载力波动较小,整体呈下降趋势;人均生态足迹增长较快,年均增长率达9.02%;能源资源人均生态足迹平均占比达87.71%,对土地资源生态影响较大;山西省土地资源一直处于强不可持续发展状态,生态系统稳定性较差,但资源生产效率逐年提高。(2)山西省各地市土地资源可持续利用情况差异较大,但均处于生态赤字状态,可持续发展能力较弱。(3)山西省2013-2022年土地资源依然处于生态赤字状态,且人均生态赤字逐年增大,土地资源生态状况不断恶化,但恶化速度与2000-2012年相比,有所放缓。针对土地资源可持续利用情况存在问题,提出相应对策建议,为推动山西省土地资源可持续利用提供数据支持和相关参考。
[Abstract]:With the development of society, the demand for land is increasing, the excessive reclamation and unreasonable use of land aggravate the limited land resources, and the ecological performance and sustainable utilization ability of land resources decrease. However, land is the material basis for human survival, and the deterioration of land resources seriously affects the sustainable development of human beings. Therefore, it is urgent to strengthen the management of land resources and improve the situation of land resources. It is very necessary to study the sustainable use of land resources. Firstly, this paper combs the theory of ecological footprint and the theory of energy value. On this basis, from the angle of energy source and utilization of land resources, a model of energy-ecological footprint of land resources is constructed. Then the model is used to calculate the ecological carrying capacity and ecological footprint of land resources. The sustainable utilization of land resources is comprehensively analyzed by ecological deficit / surplus per capita, sustainable development index, ecological footprint diversity index and ten thousand yuan GDP ecological footprint. Finally, taking Shanxi Province as an example, this paper analyzes the sustainable use of land resources in Shanxi Province from 2000 to 2012, and analyzes the spatial differences of sustainable use of land resources in Shanxi Province through ArcGIS. The sustainable utilization of land resources in Shanxi Province from 2013 to 2022 was predicted by using grey forecasting model. The conclusions are as follows: (1) the per capita ecological carrying capacity of land resources in Shanxi Province fluctuated slightly from 2000 to 2012, and the ecological footprint per capita increased rapidly, with an average annual growth rate of 9.02%; The average per capita ecological footprint of energy resources is 87.71%, which has a great impact on land resources ecology. The land resources in Shanxi Province have always been in a strong and unsustainable development state, and the stability of the ecosystem is poor, but the productivity of the resources has been improved year by year. (2) the sustainable use of land resources in Shanxi Province is different from that in the cities and cities of Shanxi Province. But they are in the state of ecological deficit and the ability of sustainable development is weak. (3) the land resources of Shanxi Province are still in the state of ecological deficit from 2013 to 2022, and the ecological deficit per capita is increasing year by year, and the ecological condition of land resources is getting worse and worse. But the rate of deterioration slowed compared with 2000-2012. In view of the problems existing in the sustainable use of land resources, the corresponding countermeasures and suggestions are put forward to provide data support and relevant references for promoting the sustainable use of land resources in Shanxi Province.
