摘要: 以新疆塔城市为研究对象,从土壤质量与景观格局角度构建评价指标体系进行耕地土壤质量与景观格局评价。结果表明,塔城市耕地土壤质量分为4个等级,Ⅰ级耕地面积占比9.95%,Ⅱ级耕地面积占比27.99%,Ⅲ级耕地面积占比37.04%,Ⅳ级耕地面积占比25.02%,Ⅰ级耕地可作为高标准耕地建设的选择对象,Ⅳ级耕地不适宜开发,需进行土壤修复;塔城市耕地景观格局分为4个等级,Ⅰ级耕地面积占比34.6%,Ⅱ级耕地面积占比40.1%,Ⅲ级耕地面积占比21.6%,Ⅳ级耕地面积占比3.7%;结合土壤质量与景观格局情况将塔城市耕地生态修复区域划分为6类,优质保护区(218 km2)、土壤质量改良区(279 km2)、土壤质量修复区(196 km2)、景观格局改良区(192 km2)、景观格局修复区(58 km2)、耕地退耕区(70 km2)。总体来看,塔城市耕地生态修复重点方向为土壤质量改良与修复。

Abstract: Taking Tacheng City, Xinjiang as the research object, an evaluation index system was constructed from the perspective of soil quality and landscape pattern to evaluate the soil quality and landscape pattern of cultivated land. The results showed that the soil quality of cultivated land in Tacheng City was divided into four levels. Grade I cultivated land accounted for 9.95%, Grade II cultivated land accounted for 27.99%, Grade III cultivated land accounted for 37.04%, and Grade IV cultivated land accounted for 25.02%. Grade I cultivated land could be used as a selection object for high standard cultivated land construction, while Grade IV cultivated land was not suitable for development and required soil remediation;the landscape pattern of cultivated land in Tacheng City was divided into four levels. Grade I cultivated land accounted for 34.6%, Grade II cultivated land accounted for 40.1%, Grade III cultivated land accounted for 21.6%, and Grade IV cultivated land accounted for 3.7%; based on the soil quality and landscape pattern, the ecological restoration areas of cultivated land in Tacheng City were divided into 6 categories: 218 km2 of high-quality protection area, 279 km2 of soil quality improvement area, 196 km2 of soil quality restoration area, 192 km2 of landscape pattern improvement area, 58 km2 of landscape pattern restoration area, and 70 km2 of farmland restoration area. Overall, the key direction for ecological restoration of cultivated land in Tacheng City was soil quality improvement and restoration.

Key words: soil quality, landscape pattern, ecological restoration, regional delineation, Tacheng City, Xinjiang
