| 摘 要： | 我国林业经济在国民经济发展中有着重要的地位,森林与气候之间也有着密切的关系。通过历史数据基于Copula函数模型验证林业经济发展与气温、降水量、湿度与日照数等气候因素之间的相关关系,林业生产总值与气温正相关,与湿度、日照数负相关。当我们认识到林业经济总产值与气温、降水量、湿度、日照数之间的相依关系和相依结构,就可以采取相应的措施。这将会对制定宏观经济发展规划与森林资源开发战略,具有一定的指导与实践意义。

| Abstract: | Forestry economy of China plays an important role in national economic development.Forest and cli mate have close relationship as well.Through the historical data and Copula function verify the relationship be tween forestry economic development and climate factors such as the temperature,precipitation,moisture and sunshine.Forestry total output value has positive correlation with temperature,however,has negative correlation with moisture and sunshine.When realize this dependence relation and dependence structure among forestry to tal output and temperature,precipitation,moisture and sunshine,should take corresponding measures.It will have guidance and practical meaning for macro economic development planning and forest resources develop ment strategy. |
