| 摘 要： | 本文以西鄂尔多斯荒漠中4种灌木--绵刺、四合木、霸王、沙冬青的地下部分为研究对象,对4种灌木所组成的多优群落内不同土壤层中各灌木生物量、根系含水量及土壤水分含量进行测定分析,结果表明成龄植株随土壤深度的增加根系的功能和吸收水分的状况也会相应变化.在同一生境中,不同物种的根系会利用不同土层的土壤水分,并确定它们之间地下部分的相互协调性.

| Abstract: | The roots of Pataninia mongolica maxim , Tetraena mongolica , Zygophyllum xanthoxylon and Ammopiptanthus mongolicus in desert of west Erdos were studied. The biomass of the four bushes, the water content of roots of the four bushes in different depthes and the water content of soil were determined. The results showed that the function and absorbing water of roots of adult plant changed with the root depth. In the same habitat, different plants use soil moisture in different depth and determine their coordination of underground parts ground of the four bushes. |
