摘要
绿色产能评价是农用地分等的进一步深化。该文在农用地分等成果基础上,结合土地质量地球化学评估,提出以产能评价、环境健康评价为主,有益元素、生态潜在风险为辅的综合性农用地评价方法,构建农用地绿色产能评价体系。最后选取吉林省西部4县(市)为研究区,进行农用地绿色产能评价,划定农用地绿色产能区。结果表明,研究区农用地总体质量良好,99.94%为绿色农田,其中绿色高产区主要分布在前郭东部和北部地区;镇赉南部及前郭北部地区有益元素丰富,大安北部及前郭西南部地区有益元素较缺乏;前郭东部地区农用地存在潜在风险,占总面积的1.5%。
Green productivity evaluation is the further extension of agricultural land classification.This paper offered to capacity assessment,environmental health assessment as the main factors,wholesome elements and ecological potential risk factors as the secondary factors for supporting a comprehensive evaluation of agricultural land to build green production evaluation system for agricultural land based on the results of agricultural land classification and geochemical soil quality assessment.Finally,this paper achieved green productivity evaluation of agricultural land and defined the area of green production by taking a case study on four counties（cities） in the western of Jilin Province.The results show that the overall quality of agricultural land is good,99.94% for the green farmland,where the green high-yield area is mainly distributed in eastern and northern regions of the Qianguo County;Wholesome elements are rich in the southern of Zhenlai County and northern part of Qianguo County,lack in the north of Da＇an County and southwest of Qianguo County;There is potential risk for agricultural land in the east of Qianguo County,accounting for 1.5% of the total area.
