- Abstract:

Yuci District is located on the eastern side of the Loess Plateau, perennial drought and little rain and higher evaporation. It is very important for regional ecological construction to explore the vegetation soil moisture and desiccation level in this region. The soil moisture content was measured by weighing method by collecting soil profile samples with a lightweight manual drill. The characteristics and desiccation effects of soil moisture in vertical profiles under different vegetation conditions(cherry forest, cultivated land, jujube forest and poplar forest)and wasteland in Yuci were studied. In addition, the availability of soil moisture and desiccation level under different vegetation conditions were evaluated. There were different levels of desiccation development in the five plantations, the poplar forest land showed the thickest dry layer(3.1 m), followed by jujube forest land(2.8 m), wasteland(2.1 m), cherry forest land(2.4 m)and cultivated land(1.5 m). The soil moisture was in the following order: cultivated land(14.53%)>cherry forest land(14.47%)>wasteland(10.70%)>jujube forest land(9.94%)>poplar forest land(8.10%). The cultivated land and cherry forest developed slightly dry layer, and the wasteland was mainly mediumdry layer, but the jujube and poplar forest land developed the moderate and heavy dry layer. For the soil moisture availability, the most of soil moisture in cultivated land and cherry forest land were low availability, soil moisture in wasteland was low availability and no availablity, while jujube and poplar forest land were no availability. Except for poplar forest land, the soil moisture of the other plantations decreased first and then increased with the increasing of soil depth. The soil moisture of cherry forest and jujube forest showed a decreasing trend within 0—3 m, and increased rapidly within 3—5 m. The distribution pattern of soil moisture in cultivated land and wasteland also decreased first and then increased, with the lowest value of soil moisture in 2—2.5 m depth. The distribution pattern of soil moisture in poplar forest was stable at first and then decreased, the soil moisture remained stable between 0 m and 3.5 m, and decreased between 3.5 m and 5 m. In all vegetation conditions of Yuci District, the dry layer developed, and the soil moisture availability was low availability and no availability. In cherry forest and cultivated land, irrigation should be maintained and increased to prevent the dry layer development, and to improve the availability of soil moisture. The soil moisture of jujube and poplar forest land were seriously insufficient, in order to ensure the sustainable utilization of soil moisture and the normal water cycle in this region, jujube and poplar forests can improve the soil moisture utilization efficiency by decreaseing density, pruning and proper irrigation.
