摘要
以沙坡头人工固沙植物油蒿和柠条为研究对象,针对水分是沙坡头植物生r长的限制因子的现实,研究了在水分条件限制下两种植物的种间关系,建立了混播油蒿、柠条种间竞争模型,验证了油蒿、柠条既竞争又稳定共存的关系,其目的为充分有效利用水资源、稳定人工生态系统提供科学依据。
Two plants Artemisia ordosica and Caragana korshinskii in Shapotou area were chosen to research.According to the fact that water is the qualified factor to the growth in the sandy area,the interspecific relationship of two plants were studied,an interspecific competition model in mixculture was set up and the relationship of competition and coexistence was examined under the condition of water restrained.The objective is to provide scientific basis for urtilizing the water resources effectively and stabilizing an artificial ecosystem.
