根据改进的内梅罗综合指数法,选择pH、有机质、碱解N、有效磷、速效钾五项因子,对冷水江锑矿区受重金属污染土壤肥力进行了综合评价,结果表明联盟和长龙界点的土壤综合肥力为贫瘠,七里铺点的土壤综合肥力为一般.依据单项指标分析,三地点土壤有机质、速效K较丰富、有效P极度匮乏,但七里铺碱解氮较丰富,而联盟、长龙界点碱解氮缺乏.土壤肥力贫瘠是导致矿区林木生长不良、成活率不高的原因之一.

The fertility index of forestry soil polluted by heavy metals in antimony is appraised with improvement nemero index by selected pH, soil organic matter, available nitrogen, available phosphorus; available potassium. The result showed that the soil fertility in Lianmeng and Chang Longjie site is poor. The soil fertility in Qilipu site is general. The soil organic matter and available potassium is enrichment but available phosphorus is poor. The available nitrogen in Qilipu site is enrichment but the available nitrogen in site Lianmeng and Chang Longjie is very poor. The poor fertility is one of cause trees growth badness and low survive ratio.
