Evaluation And Optimization Of Forest Urban Planning Index

With the development of urbanization in China,the urban ecological environment has been more and more serious damage.In order to improve the urban ecological environment,the concept of urban forest is being accepted by many cities,and the construction of forest city is inseparable from the scientific and reasonable index system The The evaluation index system of forest city is an important basis for measuring the development of forest city,whether the content of indicators is advancing with the times,directly affecting the evaluation of the status quo of forest city construction,the development of development goals,the preparation of the overall planning content,and the importance of urban forest construction The meaning of.Since the establishment of the forest city in China since the evaluation of the forest city has been revised three times and optimization,but with the development of forest city construction,the evaluation of the theory and index system research more and more attention,so the need for further forest city Index system evaluation and optimization.Based on the relevant theoretical basis,this paper puts forward the relevant application methods of the new index of forest city,and discusses the relevant indicators of urban forest in Hefei to expect the forest as the forest,and the paper analyzes the index system of the urban forest in Hefei city by means of literature review and expert consultation.The revision of the city indicator system provides a scientific basis.The main conclusions are as follows:(1)Since the creation of the forest city,China’s evaluation index has been revised and refined three times.Through comparison and analysis,it is found that the revision of the evaluation index system of the national forest city is dynamic and advancing with the times.With the study of the forest city And the development of urbanization process,the index system should also be optimized and improved.(2)Based on the analysis of the index system of the previous forest cities,the current index system in China is mainly reflected in the evaluation of the urban greening level more in the two-dimensional space;the lack of indicators to reflect the characteristics of urban forest structure;need to increase the residents to enjoy the forest city Service function of the relevant indicators.In view of the background of the indicators proposed at the time,the existing index system has been unable to meet the needs of the development of forest cities,should introduce new indicators to be improved.(3)Based on the evaluation of the current forest city index system,the urban green space system planning,the ecological city planning,the eco-city planning and other relatedurban ecological development plans,the study of its index system and the reference of foreign urban forest development The indexes of green quantity,canopy coverage and accessibility of urban forest were included in the forest city evaluation index system.(4)Based on the related field investigation,this paper discusses the qualitative and quantitative indexes of Hefei built area,and analyzes the application of new indicators,which provides scientific for the future development of urban forest in Hefei.The basis and reasonable advice.
