Evaluation of cultivated land use efficiency in Dezhou City
摘要
Abstract
This study selects 14 indexes to measure the cultivated land use efficiency in Dezhou City during 2000 to 2014 from 3 aspects of economy,society and ecology.The weight of index is determined by entropy method and the coordination between theeconomic,social and ecological benefits of cultivated land utilization.It is judged by coordination coefficient.And then,the cultivated land use efficiency of the major grain producing areas of Qingdao is compared with Dezhou.The results showed that the economic benefit and social benefit of the cultivated land utilization in Dezhou city increased steadily,respectively from 0.040 and 0.052 in 2000 to 0.262 and 0.435 in 2014,and the ecological benefit was decreased in a fluctuation,from 0.190 in 2000 to 0.070 in 2014.The coordination degree of economic,social and ecological benefits of cultivated land utilization in Dezhou during the past 15 years is relatively low,there were only 4 years at the level of basic coordination and the fluctuation is very large.The cultivated land use efficiency in Qingdao was decreased in a fluctuation.Between Dezhou and Qingdao,the gap in cultivated land use efficiency is the ecological benefits.Dezhou should pay attention to the improvement of agricultural ecological environment in the future utilization of cultivated land and control the use of pesticides and fertilizers.关键词
