冬虫夏草挖掘对藏北草原土壤破坏程度的影响研究

Effects of Cordyceps Sinensis Excavation on Soil Damage in Northern Tibet

作为一种天然植物,冬虫夏草是许多中药配方的重要组成部分,具有极高的药用价值,在市场上价格居高不下。它主要生长于青藏高原一带,藏北草原是其主要产区之一,当地牧民出于经济价值考虑对冬虫夏草进行了大面积采挖,然而这种肆意开采无形中给当地生态环境带来了巨大破坏。本文对冬虫夏草挖掘对藏北草原土壤破坏程度的影响进行研究,从土壤生物多样性、草原土壤植被、土壤化学性质三个方面对虫夏草挖掘对藏北草原土壤的破坏程度影响进行考察,设计对比试验并分析试验数据,提出相应解决措施。

As a natural plant,Cordyceps sinensis is an important component of many traditional Chinese medicine formulations.It has high medicinal value,and the price of the Cordyceps sinensis is high in the market.It mainly grows on the Qinghai-Tibet Plateau,and the northern Tibetan Grassland is one of its main producing areas.The local herdsmen have made large area mining for the Cordyceps sinensis out of their economic value.However,this kind of wanton mining has brought great damage to the local ecological environment.The effect of Cordyceps sinensis excavation on soil damage in northern Tibet was studied.From the three aspects of soil biodiversity,grassland soil vegetation and soil chemical properties,the effects of the excavation of summer grass on the soil damage in the northern Tibetan Grassland were investigated,the experimental data were designed and compared,and the corresponding measures were put forward.
