摘要
[目的]研究自然子系统和经济子系统之间的相关关系,以期为河北省新世纪10年生态系统研究提供参考依据。[方法]以河北省最近10年统计数据为具体研究对象,通过典型相关分析探讨了其生态系统中自然子系统和经济子系统之间的相关关系,分析了各变量之间的相关性。[结果]3组典型变量就能反映出两个子系统之间的典型相关关系,这主要包括:作物总产量和居民消费额之间的典型相关;农业作物生产和水产养殖业与科研开发经费之间的典型相关;森林面积和人均地区生产总值之间的典型相关。河北省经济、财政收入增长,农业生产稳步发展的同时,仍存在一些突出的问题,主要包括:居民消费额的变化与其物质性消费不成比例;社会经济发展对林木依赖性的增加,破坏了经济增长与环境保护的平衡。[结论]该研究结果为河北省新世纪10年生态系统研究提供了参考依据。
[Objective] This study aimed to provide referential basis for the new decade ecosystem study of Hebei Province by investigating the correlation between natural subsystem and economic subsystem.[Method] The correlation between natural subsystem and economic subsystem in ecosystem was discussed by means of the canonical correlation,and the correlation between variables was explored with statistical data.[Result] The canonical correlation between the two subsystems could be explained by three groups of typical variables,mainly including： the canonical correlation between crop production and consumption;the canonical correlation between agricultural crop production,aquaculture and scientific research development funds;and the canonical correlation between forest area and GDP per capita.With the growth of economy and revenue and the steady development of agricultural production,there are still some prominent problems,including the change of residents consumption is out of proportion to its material consumption;the socio-economic development depends on consuming of forests more heavily,which destroys the balance between the economic growth and environmental protection.[Conclusion] The results provide referential basis for the new decade ecosystem study of Hebei Province.
