城市森林健康与监测评价研究进展

城市森林作为城市生态系统的重要组成部分，具有重要的生态功能和社会功能。城市森林健康是保证其各项功能发挥的前提。城市森林的健康状况将直接影响城市的可持续发展。城市森林健康是一个综合概念，要求不仅满足自身生态系统的健康，还应满足人类社会的经济、文化等各方面的需求。文中分析了影响城市森林健康的因素，城市环境的特殊性和人类活动是影响城市森林健康的主要原因。介绍了我国城市森林健康监测评价指标的筛选和评价方法的选择，认为其还处于实验和摸索阶段，尚未形成一套成熟的体系。城市森林结构的破碎化等特征严重影响了城市森林的自我修复能力。为保证城市森林的健康生长，众多学者从宏观尺度和个体尺度上研究城市森林健康的维护措施。文中指出城市森林健康及其监测评价研究存在的不足之处，在总结前人研究成果的基础上提出几点建议。

A Review of Urban Forests Health and Its Monitoring Evaluation

As a key component of urban ecosystem, urban forests are of important ecological and social functions, while urban forests health is the prerequisite of ensuring the fulfillment of these functions and thus can directly affect the sustainable development of human society. Urban forests health is a comprehensive concept, which requires not only satisfying its own ecosystem health, but also meeting various demands of human society in economic, cultural and other terms. However, there are a number of factors that can influence urban forest health, while the main factors include the particularity of urban environment and human activities. In addition, the monitoring evaluation index screening and the evaluation methods selection for urban forest health in China are still at an infancy stage, which have not yet formed a mature system. The structural fragment of urban forest as well as the other features has seriously influenced the self-healing capacity of urban forests. In order to ensure the healthy growth of urban forests, many scholars researched on the maintenance measures from the macro and individual dimensions. The paper gave some recommendations in view of the shortcomings spotted in the research on urban forests health, on the basis of summarizing the previous research achievements.
