- Abstract:
-
As the most abundant biological habitat on the planet, soil ecosystem has the greatest biodiversity, and closely associated with the above-ground ecosystem. Along with the rapid economic development, disturbance by humans has become increasingly serious, and the soil biodiversity suffered significant threat. Under the background of mass extinction and the limit knowledge of soil biodiversity, it is extremely urgent for human to protect the soil biodiversity. First, we proposed a framework of threats to soil biodiversity, and analyzed the influence processes of five kinds of threats (land-use change, agricultural management, soil degradation, transgenic plants and invasive plants) to soil biodiversity at ecosystem, species and gene scales. Then, we deeply discussed the specific influence and mechanism of each threat to soil biodiversity. Finally, although researchers got some achievements about the threats to soil biodiversity, we still face lots of challenges, including the influence of specific threat to soil biodiversity at different scales, interactions and contributions among different threats to soil biodiversity, spatial explicit mapping of threats to soil biodiversity. Analysis on the potential threats to soil biodiversity can provide important information for protecting soil biodiversity, quantitative evaluation of potential threats to soil biodiversity, and urban planning.
