现实中城市绿地生物多样性保护与居民游憩利用往往相互冲突，其主要原因是缺少跨学科的理论与方法掌握居民对城市绿地生物多样性的认知及游憩偏好。因此本研究以西安城市绿地为研究对象，基于景观认知与偏好的理论，通过野外调研和游客自雇拍照研究（Visitor-employed photography, VEP）相结合的方法，明确城市绿地实际生物多样性、感知生物多样性和游憩偏好的三者关系，通过T检验和Logistic回归模型揭示主要因子对城市绿地生物多样性保护与游憩利用的影响程度，并以此为基础结合德尔菲法（Delphi Method）提出平衡两者关系的途径与措施，为权衡与协同我国城市绿地生物多样性保护与居民游憩利用的绿地规划与管理提供理论依据和实践方法。

In practice, urban biodiversity conservation often has a conflict with human recreational use due to lack of interdisciplinary theories and methods to understand the perceptions of and preference for urban biodiversity.Therefore, based on the theories of landscape perception and preference, taking the green spaces of the Xi’an City as study areas, the triangular relationships between real biodiversity, perceived biodiversity and recreational preference were examined in terms of field survey and Visitor-employed photography study. The driven factors on the perception and preference of urban biodiversity were identified based on T-test and Logistic regression model. Given the above test the results, the relevant approaches and measures will be proposed for balance urban biodiversity conservation and human recreation in urban green spaces through a Delphi study. The results of this project aim to provide theoretical basis and practical methods of urban landscape planning and management for trades-offs and synergies between urban biodiversity conservation and human recreation in future.
