| 摘 要： | 在分析地下水与土壤-植物-大气连续体GSPAC的关系基础上,系统探讨了沙地GSPAC天然植被水分系统关系,定量揭示了毛乌素沙地土壤含水率、降雨和地下水以及地下水与植被地下生物量的关系。结果表明:随着地下水埋深的增加,植被的地下生物量有明显的降低趋势;在地下水埋深小于1.8 m、降雨大于8 mm时对地下水产生不同程度影响。成果对沙地生态保护具有一定的指导作用。 |
| 关 键 词： | GSPAC 毛乌素沙地 含水率 天然植被 |

| Abstract: | Basing on the relation of Groundwater and Soil-Plant-Atmosphere-Continuous(GSPAC),the paper systematically analyzed the water relation of natural vegetation in GSPAC and quantitatively disclosed the relation of soil moisture content,precipitation,groundwater and the underground biomass of plants,putting forward a natural water requirement of vegetation in Maowusu Sandland.The results show that the groundwater level of experiment plot could significantly influence the soil moisture content of soil surface;The underground biomass of plants obviously tended to decline with increasing depth of groundwater level;As depth of groundwater below 1.8 m and precipitation above 8 mm,which have a different impact on the groundwater level.Those results had guiding important to protect ecological environment of sandland. |
| Keywords: | GSPAC maowusu sandland soil moisture content nature vegetation |
