半干旱区生态农业与生态环境可持续发展对策研究

我国半干旱区的发展与否直接影响到中国现代化的实现.然而,随着时间的推移和人口的剧增,使得人们对自然资源的需求持续扩大,再加上掠夺式经营和不合理开发,导致了本区的生态失衡、结构失调、环境污染等一系列问题,对本区的可持续性构成了威胁.本文在借鉴国外同类地区发展经验及国内大量研究的基础之上,根据本地实际,提出了黄土高原半干旱区农业与生态环境可持续发展的七条对策.

On the Sustainable Development of Agriculture and Ecosystem in Semi-Arid Areas

The semi-arid areas account for 21.7% of the total Chinese territory with 19% of the whole population inhabiting them, and the development of these areas is a key determinant in the overall development of China. The unbalanced exploitation of the natural resources in these areas, however, has caused numerous ecological, economic, social and environmental problems that pose threat to the sustainable development of the areas. The authors maintain that to solve these problems, measures ought to be taken to adjust the industrial structure, reconstruct the ecosystem, and help the few places unaffected by pollution to retain their status. The paper further proposes seven suggestions to accomplish these goals.
