    矿区耕地健康状况评价研究

    Study on health evaluation of cultivated land in mining area

    • 摘要: 矿产资源开采影响土地的物理化学性质和生态环境,矿区耕地极易受到采矿活动的破坏和污染,在土壤质量、利用条件、土壤生态状况等方面易发生变化,其物理化学性质和清洁程度影响其产出农作物是否可食用和交易,矿区耕地健康状况评价对于当地资源合理利用和食物安全供给具有重要意义。综合分析耕地质量评价相关标准及评价因素,建议矿区耕地健康状况评价从土壤质量、利用条件、土壤生态等方面选取剖面构型、有效土层厚度、表土质地、土壤有机质含量、土壤pH值、灌排条件、坡度、田块规整度、土壤微生物量和土壤酶活性、土壤重金属污染程度指标进行评价。评价方法以因素法为宜,采用百分制对指标不同级别赋分,选取部分评价单元开展试评价,科学论证试评价结果后开展整体评价。评价结果有助于明确评价单元利用条件和利用方式,可服务于农用地安全利用、制定土地复垦与生态修复方案等。

       

      Abstract: The mining of mineral resources affects the physical and chemical properties and ecological environment of the land.The cultivated land in the mining area is very vulnerable to the destruction and pollution of mining activities, and it is easy to change in soil quality, utilization conditions and soil ecology.Its physicochemical properties and cleanliness affect whether the agricultural products produced are edible and traded, the evaluation of cultivated land health status in mining area is of great significance for the rational utilization of local resources and food safety supply.The paper analyzes the relevant standards and factors of cultivated land quality evaluation comprehensively, and suggests that the health status evaluation of cultivated land in the mining area should select the profile configuration, effective soil thickness, surface soil, soil organic matter content, soil pH value, irrigation and drainage conditions, slope, field regularity, soil microbial quantity and soil enzyme activity from the aspects of the natural resources background, utilization conditions and ecological environment conditions.The pollution degree of heavy metals in soil was evaluated.The evaluation method is suitable for factor method, and the percentage system is used to assign scores to different levels of indicators, select some evaluation units to carry out trial evaluation, and carry out overall evaluation after scientific demonstration of the results of trial evaluation.The evaluation results are helpful to clarify the utilization conditions and methods of the evaluation unit, and can serve for the safe use of agricultural land, the formulation of land reclamation and ecological restoration programs, etc.
