With China's rapid economic development, the garden has been a rapid development, but due to the lack of systematic theoretical guidance, the building appears sided pursuit of beauty, built Square, repair pavilions, lawn, do not show a lot of concern for plant communities create and overall coordination of ecological processes, resulting in China's urban small-scale prevalence of vegetation, simple structure, stability and poor. Garden ecosystem as a natural ecosystem with artificial combination of special ecosystem, and how to ensure the garden ecosystem health, better play its service function to the service of humanity, and so far has not been reported, how to promote the garden ecosystem health to create a comfortable environment for the city the modern garden disciplines need to study the content. Paper system the garden ecosystem services function, and in the purifying action of the environment, biodiversity, generate and maintain, improve the microclimate role, the ability to maintain the natural soil characteristics, various disaster mitigation function, social function, a source of spiritual and cultural and educational function. The paper introduced the structure of the garden ecosystem, including species structure, spatial structure, temporal structure, trophic structure and hierarchy. The the garden ecosystem health assessment areas can be divided into biological areas, socio-economic context, the context of human health and the social public policy areas. The garden ecosystem health level, divided into morbid, unhealthy, sub-health, healthy, very healthy five levels. By vitality, resilience, and maintain the four aspects of the function of ecosystem services and population health evaluation. To establish the principle of the garden ecosystem health evaluation index system. Scientific principle, the principle of dynamic and stability, hierarchical principle embodied in the principles of interoperability and simplicity, a system of comprehensive and holistic principle, comparability principle, the principle of diversity, the principle of acceptability, human ecological principles of composition and a combination of qualitative and quantitative. Put forward the garden ecosystem health evaluation index system, including the criteria layer, feature layer and index layer. The layer includes guidelines vitality, recovery force, ecosystem service functions and population health level four aspects. Elements the layer including green level disturbed natural resilience, human tube raise degrees, environmental quality, infrastructure service conditions (including landscape architecture, comedy, signage, road paving, street lamps, rubbish bins, benches, toilets, etc. eight facilities), cultural functions, population health and the quality of the population. The index layer green investment, the change of the number of species, annual conservation of the number 28. Hunan Martyrs Park survey based on the garden ecosystem health assessment of the use of fuzzy comprehensive evaluation method proposed index system for quantitative calculations come to the health status of the martyrs park a better conclusion, with the results of the survey match. However, the restoring force of the ecosystem is poor, needs to be improved, but also the reality of the conservation and management and the garden ecosystem needs more human consistent. Improve the garden ecosystem health level the principles on the basis of theoretical analysis and practical investigation, including the principle of respect for nature, the principle of conservation of biological diversity, ecological principles, integrity optimization principle, landscape, regional and cultural principles of sustainable development principles, the principle of optimal functional and aesthetic principles of environmentally sensitive area to protect priority principle and the principle of efficiency. Proposed a raise garden eco-system health level of the recommendations, including biological regulation, environmental regulation, ecological configuration, appropriate labor management, people-oriented, vigorously publicize and increase the people's ecological awareness and public participation in awareness and garden design you want to focus on user-friendly design and so on.
