Matapopulation is an important frontier in the recent research of mathematic biology, theoretical ecology and conservation biology. The research provides new theoretic bases for the investigation of populations and species which are in severe danger, and makes forecasts and measurement for the populations\' damage due to global habitat destruction and environment deteriorism.

集合种群是当今国际数学生态学、理论生态学和保护生物学的一个主要研究前沿，其研究为濒危物种及种群的研究提供了新颖的理论依据，也为全球范围内的环境恶化和生境破坏对物种造成的伤害做出预测和度量。

The paper adopted the method of Braun-Blanquet school of vegetation ecology. Typical plots were chosen in order to investigate the vegetation type of the main parks in Kaifeng city. The analyses were based on defining the least area of communities with the usage of abundance dominancy and combining cover coefficient.
