摘要: 在1981-2000年间我国东北地区主要针茅物种的分布区调查数据,以及分布区气候数据基础上,结合针茅类生物学与生态学特征,提取影响针茅物种的12个气候因子指标。引入Gauss竞争原理及统计分析方法,建立起针茅分布竞争的随机预测数学模型,并给出相应算法。获得了2041-2050和2091-2100年针茅的最适应、次适应和可适应竞争分布区域预测图。分析表明:气候变化和种间竞争是影响贝加尔针茅、小针茅和短花针茅的中期竞争分布预测主要原因,而种间竞争是影响大针茅和克氏针茅的中期竞争分布预测的最重要原因;气候变化是影响5种针茅长期竞争分布预测的最重要原因

Abstract: Based on the actual climatic data from 1981 to 2000 in Northeast China, the predicted climatic data and the actual distribution data of Stipa species, 12 climatic factor indicators affecting Stipa species distribution were extracted combining with similar biological and ecological characteristics of Stipa. By introducing Gauss Competitive Exclusion Principle and the statistical analysis method, a competitive stochastic mathematical model of the distribution of Stipa was built, and the corresponding algorithm was given. The forecast figures were obtained for the optimal, medium and general adaptable distribution of the five Stipa species from 2041 to 2050 and from 2091 to 2100. Furthermore, by analyzing the prediction, it was shown that the climate change and inter-specific competition were the main impact factors for predicting the distribution of Stipa baicalensis Roshev, Stipa klemenzii Roshev and Stipa breviflora Griseb, and the inter-specific competition is the most impact factor for predicting the distribution of Stipa grandis P.Smirn and Stipa krylovii Roshev from the medium-term results. From the perspective of long-term results, the climate change is the important reason for affecting five Stipa species competitive distribution.
