The Relationship Between Arbor Communities and Environment in the Northwest of Liaoning Province
摘要
Abstract
In order to solve the problems in afforestation in the northwest of Liaoning Province, the paper studied the relationship between arbor communities and environment by DCCA, and used Canoco software to process the data. It is concluded that environmental factors have significant correlations among themselves. The main factors affecting the arbor community distribution are the altitude, slope, slope position and soil type. According to the DCCA sequence diagram of species and sample plots, it is found that there are five arbor communities, and the suitable growth environment of each arbor community is identified. Through the quantitative analysis of the explanation of species distribution by environment variables, the environmental factor explained 45.3%of the vegetation pattern.关键词
