At present,the accelerated pace of urbanization has intensified the demand for land use and intensified the urban-rural contradiction in land resource utilization.How to allocate the limited land in a more scientific and reasonable way has become an urgent problem to be solved between urbanization construction and farmland protection.Especially in the western region,the performance is particularly severe.There are great differences in geographical environment,climate environment and land features in Shaanxi Province,which puts forward higher requirements for the efficient and sustainable utilization of land resources in Shaanxi Province.Reasonable and efficient use of land resources has become an important guarantee to promote economic development,social progress and environmental optimization,which shows that the study of land resources utilization in Shaanxi Province is of great practical significance.Based on the situation of intensified population pressure,insufficient land supply and low utilization rate of land resources,this paper introduces the concept of sustainable land use.This paper studies the utilization of land resources from a diversified perspective and comprehensively considers the economic and ecological functions of land resources.Accordingly set up by three level indicators,as well as economic and social ecological benefits 24 secondary indexes of Shaanxi province land resources use efficiency evaluation index system,for all to affirm the target weights of the secondary uses the analytic hierarchy process,and its result is consistency check,Then,the current situation of land resource utilization in Shaanxi Province is analyzed and evaluated by using data of 10 prefecture-level cities in Shaanxi Province from 2005 to 2016.The study finds that,firstly,the utilization of land resources in Shaanxi Province is facing the situation of high overall level and unbalanced regional development.The inefficiency of regional land resources development is affected by many factors,such as regional geographical environment,economic development and so on;Secondly,by 2016,the evaluation scores of land use efficiency of 10 prefecture-level cities in Shaanxi Province have been raised from 5 high-level,4 high-level and 1 medium-level in 2005 to 8 high-level and 2 medium-level.It can be seen that the utilization efficiency of land resources is accompanied by the progress of regional economic development,and the enhancement of people’s awareness of ecological environment is also showing an increasing trend year by year.Thirdly,in 2016,the highest score of land use efficiency was 0.6113 in Xianyang and 0.3806 in Tongchuan,respectively.The unbalanced development of land use efficiency in Shaanxi Province is serious.At the end of this paper,three suggestions are put forward for the current situation and development trend of land resources utilization in Shaanxi Province.Firstly,scientific land use planning is formulated according to the current situation of land use development in Shaanxi Province,so as to ensure that the implementation of the planning can contribute to the progress of economic development,social benefits and ecological environment.Secondly,land use planning is implemented with full consideration of regional characteristics.From the point of view of regional development,we should solve the problem of land resources utilization in the region.Thirdly,we should protect cultivated land and ensure food security,so that cultivated land can no longer only be the material food to meet people’s daily needs,but also become a major contributor to ecological construction.
