摘要 | 针对黄土高原生态恢复与重建过程中水资源短缺问题,本文采用空间代替时间序列的方法对地处黄土高原
水蚀风蚀交错区的六道沟小流域在植被恢复过程中的土壤储水量和土壤垂直剖面含水量特征进行了研究,分析了
紫花苜蓿地(12,15,17,21,26,41a)、荒草地(15,32,41a)、弃耕地(12,21,41a)、杏树地(14a)的土壤储水量和土壤
垂直剖面含水量特征。结果表明:4种植被恢复方式下,土壤储水量的大小顺序为弃耕地>荒草地>杏树地>苜蓿
地;苜蓿地、弃耕地0~200cm储水量随着生长年限的延长先快速增加后缓慢减少,而荒草地的储水量随着生长年
限的延长却持续减少。水蚀风蚀交错区植被恢复过程中,植被恢复方式是该地区土壤水分变化的主要影响因素,
生长年限对土壤水分动态变化影响不明显。 |
其他摘要 | To understand the process of the variation of the soil water content in abandoned lands in the Loess
Plateau,the Liudaogou basin in the water-wind erosion crisscross region of the Loess Plateau was selected
to analyze the characteristic of soil water storage.Four land use types with different using ages were
included in this study:alfalfa land(12,15,17,21,26,41a),wild grass land(15,32,41a),abandoned
farmland(12,21,41a),and kyorin land(14a).The results showed that the order of both the average of
soil water content and the soil water storage under the four modes of vegetation restoration was abandoned
farmland> wild grass land>kyorin land>alfalfa land;The 0~200cm soil water storage of the alfalfa
land and the abandoned farmland increased firstly and then decreased gradually,and finally remained stably.
as using ages increased.However,the average 0~200cm water storage of the wild grassland decreased
with increasing utilization ages;these results indicate that the vegetation restoration mode mainly affects
the soil water content and using ages has slight effect on it during the process of vegetation restoration in
the water-wind erosion crisscross region of the loess plateau |
