Biodiversity index of agriculture and forest soils for sustainable land use

我们分析了森林和农田土壤的生物多样性和功能，以建立可持续的土地利用。森林经营没有改变土壤群落和结构，而细颗粒和微团聚体增加林龄。农田耕作对土壤生物多样性和土壤团聚体有不利影响。然而，免耕并引入杂草在短时间内增加了土壤固存。由此可见，生物活动形成的土壤团聚体是表征土壤功能的重要指标。

We analyzed soil biodiversity and functioning in forest and cropland soils to establish a sustainable land use. Forest management did not change soil community and structure, while fine particles and microaggregates increased with forest age. Cultivation of soil in cropland was detrimental to soil biodiversity and aggregates. However, no tillage with weed introduction increased soil sequestration in a short time periods. We conclude that soil aggregates which are formed by biological activities is important index for soil fuction.
