ObjectiveBuilding harmonious and healthy urban forest is an important means to solve urban problems. This study intends to explore the urban forest construction mode based on the improvement of ecosystem service function, so as to effectively guide urban forest construction and implement the concept of ecological civilization development.

MethodBased on the coastal urban forest of Qinhuangdao, Hebei Province of northern China, this paper constructs an urban forest ecosystem service function evaluation system using Delphi method, and determines the weight of each index by constructing evaluation index judgment matrix. Based on the weight comparison, the urban forest planning scheme of the project area was proposed for the purpose of improving the ecosystem service of the project. The i-Tree software component was used to simulate and calculate the ecosystem service value generated before and after the construction of urban forest, so as to verify the significance of urban forest construction based on the improvement of ecosystem service function.

ResultThe simulation results show that the urban forest construction design based on the improvement of ecosystem service function not only has important ecological significance, but also can produce great economic value, among which the forest recreation value is the most significant.

ConclusionThe regulation service, support service and cultural service functions of urban forest are the core service functions of urban forest ecosystem. According to the results of the evaluation of ecosystem service value and the situation of the study area, this study, from the perspective of the core service function, plaque build in the plant community, plant, tree species selection, biological habitat construction and recreation experience forward design scheme of the urban forest, provides useful reference for urban forest construction in warm temperate semi-humid areas.
