County-Level Quality Evaluation of Ecological Public Welfare Forest Based on GIS Technology
Ecological public welfare forest quality scientific evaluation is an important link to improve forest resource management level, and an important part of ecological public welfare forest information management system construction process. This study which by the county-level ecological public welfare forest as research object, integrate application geographic information system technology platform, use of forest resources that “second-class survey” sub-compartment database for information sources, established the county-level ecological public welfare forest geographic information management system. The ecological public welfare forest can achieve dynamic, visual and scientific management. Frequency statistics method, theoretical analysis, expert advice and other methods were adopted to screen out evaluation indexes, and AHP method was used to determine each index weight. An index system was constructed based on the “second-class survey” data to evaluate the quality of ecological public welfare forest. Finally, based on ecological public welfare forest quality evaluation index system, use of public welfare forest sub-compartment information by geographic information database was established, adopting fixed sub-compartment evaluation method to evaluation ecological public welfare forest quality
Management pattern of ecological public welfare forests in South China
The characteristics and actualities of ecological public welfare forests in South China are studied in this paper, including common and special management patterns. The restoration and reconstruction pattern of subtropical evergreen broad-leaved forests, zonal vegetation in the key eco-zone, and the transformation pattern of coniferous and broad-leaved mixed forests in the general eco-zone with multi-forms are discussed in detail. The authors also point out, based on ecological transformation and utilization, that ecological public welfare forests should be oriented to multiple benefit utilization to maintain sustainable management.
