摘要
本文在分析评价湖北大别山区农用土地资源的基础上,进行了农用土地资源带及资源类型区的划分,并对各带、区农用土地结构进行了优化与调整,然后,以资源类型区为基本单元,运用几种数学模型,求得各类型区、资源带的土地人口承载力,并提出了协调人口、资源、环境的生态经济对策。
Based on analysis and evaluation of the agro-resources and classification of land resource zone and type district, the primary potential productivity and population supporting capacity of land resource in Dabie mountainous region in Hubei Province were estimated by using mathematic models such as GM grey system model .exponential regression model and so on. The results show that the future of PSCL in 2000 is not optimistic. According to low population growth scheme the farmers' living standard in this area can only get to the state of warm and well fed type,and main agricultural products will be short except grain and plant oil. Then some eco-economic countermeasures must be taken to harmonize the relationship among land,population and environment.
