Abstract:
Xixia which is a key forest county in Henan Province was chosen as a case study area. Fixed sampling data of the forest resources from 1993 to 2013 was collected as the main information source, Landsat TM/ETM+ /OLI imageries in 1993, 1998, 2003, 2008 and 2013 were gathered as the auxiliary materials, while the 30-year comprehensive rotation was selected as the prediction period. CA-Markov was run and multi-criteria evaluation of planning scenarios was carried out on the basis of supervised classification of land use types in the study area. Research results show that: 3 planning scenarios named resource damage, ecological protection and coordinated development, were designed for the forest management planning in the study area from 2013 to 2043. The CA-Markov model shows that, compared with the land-use type in planning base period, the proportions of land-use types in 2 planning scenarios of ecological protection and coordinated development were almost the same, while the proportion of the land-use types in the resource damage were greatly different. 5 indexes of forest land use ratio, broad-leaved forest proportion, forest carbon density, forest unit area stock volume and large diameter timber proportion were calculated to evaluate the performance of 3 planning scenarios. The coordinated development scenario was the best, followed by ecological protection, and the resource damage was the worst.
