黑龍江省土地資源可持續(xù)利用評價(jià)研究
[Abstract]:Land resources are the material basis for human survival and development. The sustainable use of land resources is related to social stability and sustainable economic development. With the rapid growth of population and the need of economic development, extensive use of land resources has affected the sustainable development of China's economy and society. As an important foundation of food security, resource security and environmental security, the sustainable utilization of land resources needs the attention and attention of the whole society. On the basis of combing the relevant literature at home and abroad and taking the administrative scope of Heilongjiang Province as the research area, the paper analyzes and evaluates the sustainable land use in this area from 2005 to 2010, mainly from the perspective of land resource security. Combined with the present situation of land resources in Heilongjiang Province, the relevant evaluation indexes are selected from five aspects of productivity, production stability, economic feasibility, resource protection and social acceptability, and the weight of the index is determined by using the Analytic hierarchy process (AHP). The multifactor comprehensive evaluation model is used to evaluate the sustainable land use in the study area, and to provide practical basis for land resource utilization and management in Heilongjiang Province. The results show that the productivity of Heilongjiang Province from 2005 to 2010 showed an upward trend, but decreased in 2009 and reached a higher level in 2010. The stability of production was maintained at the medium level in 2005 and 2010, the results of evaluation from 2006 to 2009 were lower than that of 2005, and the economic feasibility gradually increased from 2005 to 2009, and decreased in 2010. The protection of resources has always been at the medium level, that is, the protection of resources is more reasonable. During the evaluation period, the index moved from the lower level to the middle high level, and the social acceptability decreased from the middle level in 2005 to the low level year by year. Contrary to the change trend of the comprehensive evaluation results, it has little effect on the comprehensive evaluation results. In short, from 2005 to 2010, the sustainable land use in Heilongjiang Province is gradually increasing, but it is in the stage of basic sustainable development, and the potential for future promotion is great. Based on this, some suggestions for sustainable land use in Heilongjiang Province are put forward, such as adjusting the structure of land use, coordinating land use and improving ecological environment construction, reconstructing the land resource utilization mode of economic and social development, and implementing strict policies and regulations.
