Relationships of soil moisture content with precipitation and evaporation in rehabilitated forests in degraded limestone red-soil region of Jiangxi Province;

In this paper geostatistical theory and methods are used to study the spatial variability and the spatial distributing characters of soil moisture of different models of rehabilitated forest in dry season in Taihe county,Jiangxi province.

The rehabilitated forest of age 10 in different models in degraded red soil region located in Taihe County and Yiyang County of Jiangxi Province was taken as the object of the study.

In this study,soil nitrogen availability and its mineralization process were examined by the methods of in situ closed-top PVC tube incubation under the different rehabilitating forest in degraded red soil in Taihe county,Jiangxi province.

In this study,soil nitrogen mineralization process and its availability were examined by themethod of in situ closed-top PVC tube incubation under different rehabilitating forests in degraded red soil.
