Loss of Ecological Value in Farmland during Farmland Conversion:A Case Study of Shaanxi Province
摘要
Abstract
We divide the the ecological functions of farmland into five types: soil conservation, water conservation, air purification, maintenance of biological diversity,entertainment and culture. Using the direct method of market evaluation,we establish the assessment model,to calculate the ecological service value of various functions, respectively, and then calculate the total loss of ecological value in farmland. Taking the case of Shaanxi Province,we calculate the total loss of ecological value in farmland in Shaanxi Province during the period 2000 -2009 at 6 366. 365 3 million yuan. Finally in order to rationally protect farmland, we put forth the following recommendations: correctly understanding the ecological benefit of farmland, and scientifically assessing the value of farmland; optimizing the industrial structure, and promoting intensive use of farmland; taking actions that suit local circumstances, and conducting rational planning of farmland use; strengthening multilateral cooperation, and establishing the common protection accountability mechanism of farmland.关键词
