珠江三角洲的人口时空变化及其对资源和环境的影响

Spatio-temporal variation of population and its influence on the resources and environment in Pearl River Delta

改革开放以来,随着珠江三角洲经济的高速发展同时,该区人口大幅增长,对资源、环境的压力不断增大,制约着该区社会经济的持续发展。本文分析了近年来该区的人口时空变化情况及其与经济发展之间的互动关系,指出人口增长使该区土地资源和森林资源人均占有量进一步降低,大气和水环境污染加重。因此,解决人口问题是实现珠江三角洲可持续发展的关键。严格控制人口,合理利用资源,优化产业结构,增加环保投资和加强区域整体协调是珠江三角洲实现可持续发展的基本对策。

Since the practice of reform and open-door policy, the economy in the Pearl River Delta has been developed rapidly, with the population growing up significantly, which made a greater pressure on the resources and environment, and restricted the regional economic and social sustainable development. In this paper, the recent years＇ temporal-spatial variation of population and its relationship with the economic development of this area were analyzed, and the results indicated that due to the increase of population, the possess of land and forest resources per person was further decreased, and the air and water pollution became more serious. It was of significance to solve the population problem for the sustainable development in Pearl River Delta. Strictly con- trolling population growth, rationally utilizing natural resources, optimizing economic structure, increasing investment for environment protection, and strengthening regional cooperation should be the essential countermeasures for realizing the sustainable development in this area.
