摘  要：
为了实现低山丘陵区退化生态环境的高效修复,筛选出适合该地区推广种植的植被修复模式,采用定位监测法,对典型月份下6种植被的土壤水分时空变化规律进行了分析。结果表明,植被土壤水分在不同月份间具有较大的变化,且呈现出一定的变化规律。对所有植被而言,表层土壤的水分变化较大,深层土壤的水分变化较小,土壤水分变化随土壤深度呈先减后增再减的趋势;所有植被土壤水分在所监测的月份中均呈倒"S"形分布,且11月份水分变化幅度略大于4月份和7月份;与其他植被相比,刺槐+苜蓿和荒草地在所监测月份的土壤水分中综合表现较好;同时,每种植被的土壤水分也都呈现出自身特定的时空变化规律。

摘  要：
In order to realize the effective restoration of the degenerative environment in hilly region and select the suitable vegetation restoration models, the dynamic changes of soil moisture of 6 vegetations under the representative months were analyzed with the fixed monitoring on the field. The results showed that the soil moisture of vegetations varied greatly in the different months and had definite characteristics. For all the vegetations, the variation of soil moisture in soil superficial layer was greater than that in soil deep layer, and with the soil depth increased, the tendency of the variation for soil moisture was: firstly decreased, then increased and finally decreased. The distributions of soil moisture for all vegetations present fall-S shape in the investigated months, and the variation extent of soil moisture in November was greater than that in April and July. According to the comprehensive analysis for all the vegetations, the soil moisture of locust+alfalfa land and wild grass land was better compared to other vegetations. In addition, the specific characteristics of soil moisture variation for every vegetations were also found.
