摘　　要：按照土地可持续利用的要求,建立了小尺度采煤沉陷地复田景观质量评价的三级指标体系,尤其是对景观生产力、景观健康水平和景观美学价值这3个二级指标及其以下的三级指标给予了明确的界定,提出了各个指标的衡量标准与方法以及复田景观质量综合定量评价方法,利用内插中值法建立了5级质量评价标准,当评价指标LA<0.7时为优质;0.7≤LA<1时为较优质;1≤LA<1.5时为一般;1.5≤LA<2.1时为较劣质;LA≥2.1时为劣质,并在山东兖州某采煤沉陷地复垦项目中得到了验证.According to the requirements of sustainable utilization, the three-levels＇ quality evaluation system for reclaimed farmland landscape was established. The index system mainly includes three second-levels＇ indexes such as landscape productivity, landscape health level and landscape aesthetics worth and three-levels＇ indexes hereinafter were definite limited. This study identified every index and presented their evaluating standard and methods, and a comprehensive and quantitative evaluating method for the reclaimed farmland landscape quality assessment was presented. By means of inner insert median method, five grades of quality evaluating standard was established, when the value of LA is less than 0. 7, its quality is excellent ; when the LA is within 0. 7 and 1, its quality is relative excellent ; when the LA is within 1 and 1.5, its quality is in the middle grade ; when LA is within 1.5 and 2. 1, its quality is relative poor; when the LA is larger than 2. 1, its quality is in the most poor grade. A satisfy result was got by a case study of subsided land reclamation in Yanzhou City , Shandong Province.
