桉树人工林土壤生物多样性问题研究

Problems and Countermea sures of Soil Biodiversity in Eucalyptus Plantations

桉树人工林土壤生物多样性是桉树人工林生态系统生物多样性的一个组成部分,至今尚未引起人们足够重视。土壤生物多样性较其它人工林和天然林低,由于土壤生物多样性受地面植被和动物的多样性以及土壤内部的生境所制约,因此,要提高桉树人工林生态系统的土壤生物多样性,就必须从增加林下动植物的多样性入手。这才是解决问题的根本办法,也是促使桉树人工林生态系统回归到动态平衡的健康状态的根本保证。

Soil biodiversity in eucalyptus plantations is a componentpart of the biodiversity in the eucalyptus plantation ecosystem.Up to now,it has not received enough attention.Soil biodiversity in eucalyptus plantations is lower than that i n other plantations and natural forests.Soil biodiversity is correlated with the diversity of vegetations and animalson the groundand the inner environmentsof the soil.Therefore,to increase the soil biodiversity in the eucalyptusecosystemmuststart with the increase of diversity of plants and animals in the plantation.This is essential for solving the problemand ensuring that the eucalyptus plantation ecosystem returns to dynamically balancedhealthy state.
