摘要
本文依据磴口县光、温、水、土等自然要素第一性物质的生产潜力,在土地利用结构合理调整的基础上,按不同的消费水平,估算了磴口县在公元2000、2020年土地对人口的承载能力,并提出了合理的人口发展规划。
Dengkou County of Inner Mongolia is selected to study population car-
rying capacity on land resources in desert area. The carrying capacity of
a certain area will tell us the potentials for man to use the land resources,
or to what extent can it support human survivals. The paper firstly pre-
diets the scales and levels of future production, then tries to get how
many people can be reared in the county.
A few methods were compared to seek for the best one through that
the problem was to be solved, at end, linear programming was recognized
and unconventionally used. By 3 schemes of food consumption standards,
A (Lower), B (higher) and C (middle), Dengkou land resources can res-
pectively support populations of 447001, 345146 and 385929 by 20000. If
we consider cereal per capital as only consumption index, the cereal output
of the county can support 671000 people by 2020, the maxmum of population
supported by natural potential productivity is 848000. In the very end of
the essay a population plan is simply discussed.
