- Abstract:
- The study took three small watersheds in different vegetation zones of Yanhe River valley as the research areas. It treated SHI as soil evaluation index, and took the soil moisture combination with land use distribution of different vegetations and its soil moisture as the method, which made an analysis of the soil water content along the river basin. In addition, a scientific basis for the rational use of water and soil resources of different vegetation zone was provided. The results show that the three vegetation zones were extremely dry, the order of soil moisture was forest steppe region, forest region and grassland. The forest region was based on woodland, forest steppe region was forestland and grassland, steppe region was grass. There is significant difference among those soil water contents, forest region was higher than forestland and grassland, and grassland was the lowest. According to the analysis on soil water content profile in different vegetation zones, it showed that soil water content increased with depth in 0—200 cm soil layer and had a growth tendency. Therefore, among four ways of land use, soil moisture content of farmland was significantly higher than the other land uses, not only because it was mainly affected by smaller slope and terraces, but also the smaller crop water consumption. There was no significant difference in soil water content between forestland and grassland. Moreover, soil water content of shrub land is minimal.
