【摘要】：土地的承载力是可持续发展的重要体现,伴随着大规模的城市化,占用了越来越多的土地资源,实现土地资源的可持续性发展也已成为社会发展追求的目标,因此,对土地资源承载力评价研究已成为一个热点问题。沈阳经济区是国家重要装备制造业基地和辽宁省经济发展的核心区域,国土空间人口和产业集聚明显,城镇化率较高,是全国第四大城市群；同时,沈阳经济区国土空间资源总量丰富,耕地、森林、草地、水资源量分别为2.83万平方公里、3.13万平方公里、0.19万平方公里、147.40亿立方米；能源和矿产资源种类齐全,铁、煤、菱镁石、滑石、玉石、大理石等矿产资源储量均居全国重要地位,当前沈阳经济区经济、人口、社会等都对水土资源、环境造成了压力,生态保护区、老工业基地振兴区、贫困地区与快速城镇化地区的城乡统筹和区域统筹发展等问题突出。本研究以此为切入点,重点研究沈阳经济区土地资源承载力评价问题,主要内容如下：(1)第一、二部分,首先阐述了选题依据,强调了本文选题的意义,再次归纳国内外研究现状,最后构建论文框架和技术路线,从可持续发展理论、土地生态理论、土地资源永续利用、生态脆弱性理论以及生态足迹理论等几个方面梳理了主要的土地承载力相关理论。(2)第三、四部分,对土地资源承载力的可持续性进行评价分析。其分为两类：一类是基于土地分类的土地资源承载力评估,侧重点是对耕地人口承载能力评价和建设用地人口承载能力评价；结合两种土地类型评价结果的基础上进行了土地资源承载能力综合评价。二是基于生态足迹的土地生态系统承载力评价,重点在于研究区土地生态系统概况和土地生态系统承载力评价,并对研究区未来的生态系统承载力进行了有关预测。(3)第五、六部分,结合目前沈阳经济区的土地利用总体形势与对经济区的承载力评价分析成果,以生态基质、生态斑块和生态廊道三大要素构建研究区的生态基础设施格局,提出沈阳经济区土地资源优化配置的政策建议。
[Abstract]:The carrying capacity of land is an important embodiment of sustainable development. With the large-scale urbanization, it occupies more and more land resources, and realizing the sustainable development of land resources has become the goal of social development. It has become a hot issue to evaluate the carrying capacity of land resources. Shenyang economic zone is the core region of the national important equipment manufacturing base and Liaoning province economic development. The land and space population and industry agglomeration is obvious, the urbanization rate is relatively high, and it is the fourth largest urban agglomeration in China. At the same time, Shenyang economic zone is rich in total land and space resources. The amount of cultivated land, forests, grassland and water resources are 28300 square kilometers, 31300 square kilometers, 1900 square kilometers and 14.74 billion cubic meters respectively. There are a wide range of energy and mineral resources, such as iron, coal, magnesite, talc, jade, marble and other mineral resources, all of which occupy an important position in China. At present, the economy, population and society of Shenyang's economic zone are all exerting pressure on water and soil resources and the environment. Ecological reserves, old industrial base Zhenxing district, poor areas and rapid urbanization areas of urban and rural planning and regional overall development problems. The main contents of this study are as follows: (1) the first and second parts, firstly, the basis of the topic is expounded, and the significance of the topic is emphasized. At last, the thesis frame and technical route are constructed, from the theory of sustainable development, the theory of land ecology, the sustainable utilization of land resources. Ecological vulnerability theory and ecological footprint theory and other aspects of the main related theories of land carrying capacity. (2) the third and fourth parts, the sustainability of land resources carrying capacity evaluation analysis. It can be divided into two categories: one is the assessment of carrying capacity of land resources based on land classification, the emphasis is to evaluate the carrying capacity of cultivated land population and the population carrying capacity of construction land; Based on the evaluation results of two types of land, the comprehensive evaluation of carrying capacity of land resources is carried out. The second is the evaluation of land ecosystem carrying capacity based on ecological footprint, which focuses on the general situation of land ecosystem and the evaluation of land ecosystem carrying capacity in the study area. The future ecosystem carrying capacity of the study area is forecasted. (3) the fifth and sixth parts, combined with the overall situation of land use in Shenyang Economic Zone and the results of the evaluation and analysis of the carrying capacity of the economic zone, are based on the ecological matrix. The ecological infrastructure pattern of the study area is constructed by the three elements of ecological plaque and ecological corridor, and the policy suggestions on the optimal allocation of land resources in Shenyang Economic Zone are put forward.
