| 摘 要： | 以滩涂裸地为对照,对黄河三角洲贝壳堤向海侧的盐生灌草、滩脊地带的旱生灌草及向陆侧的盐生草3种植被类型的土壤水文功能进行了研究。结果表明,与裸地相比,贝壳堤生境条件下的盐生灌草、旱生灌草及盐生草3种植被类型土壤容重降低了8.5%~20.8%,总孔隙度增加了17.1%~46.1%。滩脊地带的旱生灌草改善土壤孔隙状况效果最好,向陆侧的盐生草最差。3种植被类型具有一定的压碱抑盐效应,降盐碱功能表现为滩脊地带的旱生灌草最好,其次为向海侧的盐生灌草,而向陆侧盐生草最差。不同被覆地类土壤渗透性能大小表现为:向陆侧盐生草滩脊地带旱生灌草向海侧盐生灌草裸地。0—40cm土层的土壤饱和贮水量和毛管贮水量表现为:滩脊地带旱生灌草向海侧盐生灌草向陆侧盐生草。在垂直层次上,贝壳堤不同植被类型改良盐碱、土壤孔隙状况及贮水性能均表现为0—20cm优于20—40cm土层。研究表明,贝壳堤滩脊地带旱生灌草植被的土壤贮蓄水分及降盐改土能力最优,其次为向海侧的盐生灌草,向陆侧的盐生草较差。

| Abstract: | Compared with bare land, soil hydrological characteristics of three kinds of saline bringing, xerophytic bringing and saline herbaceous were researched in shell ridge island of the Yellow River Delta. Results indicated that compared with bare land, the soil bulk density of three vegetation types decreased by 8.5%~20.8%, soil total porosity increased by 17.1%~46.1%, the effect of xerophytic bringing vegetation in beach ridge zone was the best, the effect of saline herbaceous vegetation close to landside was the worst. The sequence of the soil permeability characteristics of different vegetation types was in the following increasing order: saline herbaceous vegetation close to landside < xerophytic bringing vegetation in beach ridge zone < saline bringing vegetation close to the seaside < bare land. The sequence of the soil saturated water and capillary water of the soil layer in 0-40 cm was in the following decreasing order: xerophytic bringing vegetation in beach ridge zone > saline bringing vegetation close to the seaside > saline herbaceous vegetation close to landside. The soil water storage performance and improved effect of the soil layer in 0-20 cm were better than that in 20-40 cm. The ability of soil water savings, salt reducing and soil improving of xerophytic bringing vegetation in beach ridge zone was the best, that of saline herbaceous vegetation close to landside was the worst. |
