中文摘要 | [目的]研究不同治理措施下土壤结构及土壤水分的分异特征,为合理选择沙化土地治理方式提供科学参考。[方法]结合空间代替时间和相邻样地比较法,利用压力膜仪和烘干法对科尔沁沙地治理过程中形成的樟子松人工林地、小叶杨人工林地、小叶锦鸡儿林地、围封草地、天然恢复的固定沙地以及流动沙地(CK)土壤水分特征曲线及土壤结构进行研究。[结果] ①各种治理措施均能明显增强土壤水分持蓄能力,小叶锦鸡儿林地土壤有效水含量最高,为0.05 cm~3/cm~3。②各治理措施土壤沙粒含量、土壤容重降低;小叶锦鸡儿对土壤粉粒恢复效果最高,较流动沙地增加7.49%;围封措施下土壤黏粒含量最高,为1.08%。③土壤黏粒是影响土壤有效水含量和过剩水含量的主要因素,回归系数分别达到2.54和-2.65。[结论]小叶锦鸡林地和围封措施能较好地改善沙化土地土壤结构和土壤水分持蓄能力。 |
英文摘要 | [Objective] Characteristics of soil moisture and soil structure in different land types were studied, and the responses between them were analyzed, to provide a scientific reference for reasonable selection of desertification control. [Methods] Space-time-substitution and paired-sites methods were combined to research soil characteristics in lands with Pinus sylvestris plantation, Populus simonii plantation, Caragana microphylla community, and fencing land, fixed sandy land and shifting sandy land. Soil water characteristic curve was established by membrane pressure gauge, soil mechanical composition was analyzed by laser particle analyzer, soil bulk density was measured by oven drying method. [Results] ① Soil water holding capacity was significantly enhanced by the treatment measures, soil available water content in Caragana microphylla community was the highest of all control measures, which was 0.05 cm~3/cm~3. ② The soil sand content and soil bulk density were decreased in each treatment. Caragana microphylla community had the best recover effect on silt content, it was 7.49% higher than that of shifting sandy land. The highest clay content was observed in fencing land which was 1.08%. ③ Soil clay content is the main factor affecting soil available water and excess water, the regression coefficients of soil clay content to available and excess water were 2.54 and -2.65, respectively. [Conclusion] Caragana microphylla community and fencing treament can improve the sandy land soil structure and soil water holding storage capacity. |
