Abstract:

With the increasing problems of the ecological environment,the assessment of damage to forest ecological services and functions has gradually become an important issue in the construction of environmental rule-of-law.However,there is no such evaluation index system for the damage to forest ecological services and functions in Guangdong Province.Using the analytic hierarchy process (AHP) method,we constructed an assessment system for forest ecological environment damage,which is approximately equivalent to the loss of forest ecological services and functions and is suitable for fast evaluations at small spatial scales.By absorbing existing assessment methods of forest ecosystem service functions,we combined the six major ecological function zones in Guangdong Province and utilized expert scoring and the analytic hierarchy process to establish a new evaluation index system,including regulatory services,support services,and supply services.Through weight analysis,the regulatory service in the Nanling Mountain District had a high weight of 0.507,highlighting its core role in water conservation and pollution purification.The weight of support services in the central Guangdong region was 0.475,reflecting that soil and water conservation was crucial for maintaining the ecological security of the region itself.Supply services had a prominent weight in coastal areas (0.412),mainly due to the high economic value and biodiversity conservation functions of mangrove forests in this region.Therefore,through the AHP quantitative evaluation,there were differences in the dominant service types of different ecological functional areas,and protection strategies should be formulated according to local conditions.This result would provide a scientific basis for the protection and ecological restoration of forest resources in diverse regions across Guangdong Province,and points out the need to further optimize the objectivity of evaluation indicators and improve the legal framework to enhance the operability and scientificity of the damage assessment of forest ecological services and functions in the future.

Key words: Analytic hierarchy process (AHP), damage of forest ecological environment, ecosystem service, ecological function planning, Guangdong Province
