基于投影寻踪模型的林业产业生态系统和谐性研究

以林业产业生态系统为着眼点,运用投影寻踪模型对黑龙江省林业产业生态系统和谐性进行了研究。结果显示:林业产业主体系统和谐度显著小于模型设定的阈值,这表明林业产业生态主体系统在研究时间范围处于微观不和谐状态,分别是一年、四年、两年、三年和一年处于严重失调、中度失调、基本和谐、中度和谐、良好和谐的状态。依据判别模型得出:黑龙江省林业产业生态系统不和谐,从而提出了林业产业规模调整和结构优化的建议。

Study on the Harmonious State of Forestry Industry Ecosystem Based on Projection Pursuit Model

Focusing on forestry industry ecosystem,using projection pursuit model for measurement of harmonious state of forestry industry ecosystem of Heilongjiang province,the results showed that harmonious degree of the principal system of ecological forestry industry is significantly less than the threshold set in model,indicating that in the this study time range the principal system of ecological forestry industry was in the microscopic state of disharmony. The state in serious imbalance,moderate disorders,basic harmony and good state of harmony were separated one year,four years,two years,three years and one year. According to the model,forestry industry ecosystem of Heilongjiang province was in disharmony state,and forestry industry sizing and optimization recommendations were proposed.
