Some of these changes in YLX, WJB, and HQ are enlarged and illustrated in Figure 5. Looking into the detailed changes, as shown in Figure 5, it is found that in YLX, the streams based on TI1 and TI3 turn from an area covered with Mollic Gleysols (GLm) to a place covered with Gelic Leptosols (LPi) at the point labeled A1. As to the impacts of K, the stream based on TI2 turns from LPi to GLm at A2. In WJB, the streams based on TI1 and TI3 turn from Eutric Planosols (PLe) to Dystric Cambisols (CMd) at point B1. The stream based on TI2 turns from Eutric Fluvisols (FLe) to PLe at B2. In HQ, the streams based on TI1, TI2, and TI3 turn from Haplic Acrisols (Ach) to Cumulic Anthrosols (ATc) at C1 and C2. The K_s, K,and K_s·K values of the mentioned soils are listed in Table 3.
