为了探明旅游活动对张家界国家森林公园土壤微生物活性及多样性的影响,保护土壤生态平衡及合理开发自然保护区提供理论依据,进行了旅游踩踏对土壤微生物生物量碳、氮、磷的影响研究.结果表明,在所设的3个试验区中,0～5cm土壤层的微生物生物量碳、磷受到旅游踩踏的影响最严重,5～15cm土壤层的微生物生物量碳、磷受到旅游踩踏的影响较严重,而15～25cm土壤层的微生物生物量碳、磷受到旅游踩踏的影响最轻,旅游踩踏对所设3个试验区中3个层次土壤的微生物生物量碳、磷的影响均达到了显著水平(p＜0.05).从旅游踩踏对3个土壤层的微生物生物量氮的影响程度来看,0～5cm土壤层的微生物生物量氮受到的影响最...

Ecological environment was destroyed by recreation activities. In order to probe into the effect of recreation activities on microbes in soil and to provide useful development suggestion, the studies on the effect of recreation on microbial biomass carbon, microbial biomass nitrogen and microbial biomass phosphorus in soil from Zhangjiajie National Forest Park were conducted. The results showed that： When soils from control zero, buffer zero and active zero were used for analysis, the microbial hiomass carbon and phosphorus from 0 - 5 cm layer...
