人口、资源、环境与贫困——以甘肃中部18个贫困县为例

Population, Resource, Environment and Poverty —a case study on the 18 underdeveloped counties in Central Gansu

从人均占有粮的变化看，甘肃中部在５０年代以来的大部分时间里处于“有增长而无发展的状态”。形成这一状态的主要原因是人口的持续增长和为缓解人口压力不断扩大的垦殖及由此造成的生态环境的严重退化。贫困既是人口性的，又是资源环境性的，归根结蒂是人口—资源（环境）性的：少量的人口可以同差的环境相适应，高的生产力也难以承受不断增加的人口压力。控制和减少人口。

From 1950s till now, the grain per head in central Gansu has been increasing but not developing. The main reasons for this are constant population increase, constantly enlarged cultivation of land against population pressure and the resultant severe ecological degeneration. Poverty is caused both by population and by environment and resources, and fundamentally by the combination. A small scale of population can coordinate with bad environment but high production can not bear a large scale of population growth. To controll and reduce population, and to raise population environment suitability are the key approaches restraining ecological degeneration and further reducing poverty.
