Abstract

The present study was conducted at a coal mining affected forest and a non-affected forest to analyze the seasonal changes in soil physico-chemical properties, incorporate additive and weighted soil quality index (SQI) to determine the soil quality and check the affected forest soil pollution status. Comparative SQI shows that the non-affected forest presented higher SQI in all the seasons (winter, spring, summer and autumn). However, in both the forest the seasonal additive and weighted SQI was categorised as autumn > summer > spring > winter and the overall SQI of the soil depth was ranked as 0–10 > 10–20 > 20–30 cm. The Single pollution index (PI) points out that cadmium (Cd) was the main potential contributor to soil pollution while the Pollution load index (PLI) and Nemerow integrated pollution index (NIPI) revealed moderate soil pollution status. The result summarized that coal mining activities can elevate soil deterioration rate, such as loss in soil organic carbon, reduction in nutrient availability, and slowing down the rejuvenating process of forest soil.

印度那加兰昌基煤矿影响森林的土壤质量评价

本研究在一个受煤矿影响的森林和一个未受影响的森林中进行，以分析土壤理化性质的季节变化，并结合添加剂和加权土壤质量指数（SQI）来确定土壤质量，并检查受影响森林的土壤污染状况。比较SQI表明，未受影响的森林在所有季节（冬季、春季、夏季和秋季）都表现出较高的SQI。然而，在这两种森林中，季节相加和加权SQI被分类为秋季>夏季>春季>冬季，土壤深度的总体SQI被排序为0–10>10–20>20–30 cm。单一污染指数（PI）指出镉（Cd）是造成土壤污染的主要潜在因素，而污染负荷指数（PLI）和Nemerow综合污染指数（NIPI）则表明土壤污染处于中等水平。结果表明，煤炭开采活动可以提高土壤退化率，如土壤有机碳的损失、养分有效性的降低和减缓森林土壤的恢复过程。
