Abstract
Research content: The intrinsic attributes of mountainous areas, namely vulnerable ecology and highly sensitive environment, are highly restricting sustainable utilization of arable land in mountain areas. At present, the research is more detailed on the evaluation of sustainable utilization of arable land in mountainous areas in borderland, and evaluation of sustainable utilization of arable land in mountainous areas is one of the important bases for ensuring food security, maintaining border stability, and promoting sustainable economic and social development. With Yunnan Province as an example, on the basis that the special connotations of sustainable utilization of arable land in mountainous areas are explained, in combination with the Second National Land Survey, the index system is constructed from 3 perspectives, eco-friendliness, economic feasibility, and social acceptability, and variation coefficient method and comprehensive index method are used to calculate the level of sustainable utilization of arable land and for grading. Research method: Progress in research on evaluation of sustainable utilization of arable land is learnt by literature review, and the research area is empirically analyzed by method of comparative analysis and qualitative-quantitative combined method. Conclusions: The arable land in the mountainous areas of Yunnan Province is generally in a state of sustainable utilization. Moderately sustainable and unsustainable cities and prefectures are almost equal, but there is no sustainable city or prefecture. In terms of spatial distribution, the level of sustainable utilization of arable land in mountainous areas is lower especially in mountains and highlands of the northeast Yunnan, and high mountains, highlands and canyons of the northwest Yunnan. Most of those areas are subject to a level of unsustainable utilization. The level of sustainable utilization of arable land in mountainous areas is higher in middle and eastern Yunnan.
Highlights
Sustainable utilization of arable land is an important measure to protect the ecological environment of arable land, guarantee national food security, safeguard national long-term stability, and realize a harmonious society
In order to fully and systematically promote the sustainable utilization of arable land, many experts and scholars in China have performed theoretical discussions and empirical researches on the evaluation of sustainable utilization of arable land, which mainly focuses on building of the index system [1,2,3,4,5,6], empirical research on areas based on model and theory [7,8,9,10], and etc
On the basis of results of the Second National Land Survey, evaluation index system of sustainable utilization of arable land in mountainous areas is constructed from 3 perspectives, eco-friendliness, economic feasibility, and social acceptability, and weight is confirmed by coefficient of variation so as to evaluate and analyze sustainable utilization of arable land in mountainous areas in Yunnan[15]
Summary
Sustainable utilization of arable land is an important measure to protect the ecological environment of arable land, guarantee national food security, safeguard national long-term stability, and realize a harmonious society. It is an important part of sustainable socio-economic development and has been highly valued and widely implemented in China. On the basis of results of the Second National Land Survey, evaluation index system of sustainable utilization of arable land in mountainous areas is constructed from 3 perspectives, eco-friendliness, economic feasibility, and social acceptability, and weight is confirmed by coefficient of variation so as to evaluate and analyze sustainable utilization of arable land in mountainous areas in Yunnan[15]. Sustainable utilization of society means that an increasing number of humans can be fostered with limited resources, delivers level of social acceptability and social affordability, and reflects a measure of intergenerational equity
