Estimation of Applicability of Soil Model for Rubber (Hevea brasiliensis) Plantations in Xishuangbanna, Southwest China

Soil water content (SWC) plays a vital role in the process of evapotranspiration (ET) rubber plantations. To investigate influence ET on soil balance plantations, we measured SWC at depths 10, 20, 30, 40, 70, 100, 130 cm, characteristics root density distribution, and estimated deep percolation plantation Xishuangbanna using Hydrus-1D model. Our results indicate model can accurate simulate dynamics 0–130 cm plantations with Nash-Sutcliffe Efficiency Coefficient (NSE) was 0.80–0.96, Root Mean Squared Error (RMSE) 0.05–0.02, Pearson Correlation (R) 0.82–0.97. Obviously, there were seasonal variation moisture changes Xishuangbanna. The storage (SWS) dropped to its lowest value 194 mm reached maximum 504 from dry season rainy season. simulated 1166.1 mm. large uptake utilization by affects or exacerbates drought leads shortage regional resources.
