| Abstract: |
| The division of ecological region is the base for the management and continual development of natural resources.It provides construction of ecology and environment and making of environmental management policies with scientific basis.After synthetic analysis of ecological and environment features of the Loess Plateau,the ecological stage and main ecological problems of the area are cleared.According to its natural features,similarities and differences of internal structure,we got the principles,basis and inductors for sub region of the Loess Plateau through cluster analysis of climate parameters,soil parameters,cover parameters and other social and economic factors.Then seven first grade sub regions are got,also the missions and way of ecology construction and structure of eco-system for every sub-era are provided. |
