生态脆弱带内部经济结构的调整探讨─—以四子王、商都、张北剖面为例

RESEARCH ON THE ECONOMIC STRUCTURE REGULATION IN THE ECOLOGICALLY FRAGILE ZONE──A Case Study in Siziwang, Shangdu and Zhangbei Regions

内蒙古乌盟后山、河北坝上是中国北方生态脆弱带中最为脆弱的地段。经济发展水平低，产业结构不合理，荒漠化严重。通过采取“中小企业群地”的工业发展策略，压缩耕地、增加林牧比重，加强基础建设等措施，积极发展第二、三产业，以求建立生态经济协调发展的良性结构。

The Houshan region in Inner Mongolia and Bashang region in Hebei Province are two most fragile ecological zones in northern China. In these areas economical development is still in a lower level due to unreasonable industrial structure and serious land desertification.To establish a benign structure for ecologically and economically harmonious development some measures have to be adopted,such as establishing medium- small enterprise group;cutting down cultivation land but increasing afforestation and pasture areas;strengthening capital construction and actively developing second and third industries etc.
