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长的限制因子的现实 ,对混播油蒿、柠条种间竞争模型平衡点的稳定性进行了分析 .对于优化防护林的布置格局 ,建立相对稳定的防风固沙人工群落 ,具有现实意义 ;对充分有效地利用水资源 ,合理规划设计防护林 ,稳定人工生态系统提供科学依据 ,在理论与实践上具有重要意义 .
The article chose two sandfixing plants Artemisia ordosica and Caragra korshinskii in Shapotou area as the study objects,according to the fact that water is the limited factor of plant's growth.We analysis the equilibrium points stability of interspecific competition model.This work has reality to optimize the style and build comparable stable manmade community.It provides science basis for using water resources,designing shalter balt and stabilizing manmade ecological system.It has important meaning both in theory and practice.
