- Abstract:

Soil is an integral part of ecosystems and also is the basis for vegetation succession and development. Detecting the response of soil nutrients to different restoration approaches can be of great importance to restoration planning. The present study compared the difference of soil nutrients between natural and artificial vegetations under different succession stages. The results showed that the soil nutrients such as organic matter, total and nitrate available and available potassium in artificial vegetations was higher than that in natural vegetations with exceptions to total and available phosphorus after 6 years. However, after 20 years, the differences of soil nutrients between the two approaches became narrower, and the soil organic matter in natural vegetations even higher than that in artificial vegetations. This conclusion has great implications on the restoration planning. For example, we can use the artificial vegetation to accumulate the nutrients quickly and improve the soil fertility, and then introduce the zonal species to manage these artificial vegetations.
