选取甘肃祁连山国家级自然保护区天祝三峡森林公园、焉支山森林公园、大野口森林公园和马牙雪山生态旅游景区、窟窿峡生态旅游景区、康乐草原生态旅游景区等6个样地,对该自然保护区土壤的物理性状和化学性状进行了监测分析。结果表明,在游客数量多、干扰强烈的区域,游客对土壤践踏严重,土壤孔隙度减低,容重增加,含水量和有机质含量减少,pH 值增大,氮、磷、钾含量减少,肥力下降。
選取甘肅祁連山國傢級自然保護區天祝三峽森林公園、焉支山森林公園、大野口森林公園和馬牙雪山生態旅遊景區、窟窿峽生態旅遊景區、康樂草原生態旅遊景區等6箇樣地,對該自然保護區土壤的物理性狀和化學性狀進行瞭鑑測分析。結果錶明,在遊客數量多、榦擾彊烈的區域,遊客對土壤踐踏嚴重,土壤孔隙度減低,容重增加,含水量和有機質含量減少,pH 值增大,氮、燐、鉀含量減少,肥力下降。

Physical and chemical properties of soil were determined by selecting six samples (Tianzhu Three Gorges Forest Park,Yanzhishan Forest Park,Dayekou Forest Park and Horse-teeth Mountain eco-tourism area,hole gorge eco-tourism attractions,Kangle Grassland eco-tourism area)in Gansu Qilian Mountains National Nature Reserve. Result shows that in the region with larger number of tourists and strong interference,tourists trample soil serious-ly,soil porosity reduce,bulk density increase,moisture and organic matter content reduce;pH value increases,nitro-gen,phosphorus and potassium content reduce,fertility decline.
