Relationships between Human Disturbance and Wildlife Land Use in Urban Habitat Fragments

Abstract: Habitat remnants in urbanized areas typically conserve biodiversity and serve the recreation and urban open‐space needs of human populations. Nevertheless, these goals can be in conflict if human activity negatively affects wildlife. Hence, when considering habitat remnants as conservation refuges it is crucial to understand how human activities and land uses affect wildlife use of those and adjacent areas. We used tracking data (animal tracks and den or bed sites) on 10 animal species and information on human activity and environmental factors associated with anthropogenic disturbance in 12 habitat fragments across San Diego County, California, to examine the relationships among habitat fragment characteristics, human activity, and wildlife presence. There were no significant correlations of species presence and abundance with percent plant cover for all species or with different land‐use intensities for all species, except the opossum (Didelphis virginiana), which preferred areas with intensive development. Woodrats (Neotoma spp.) and cougars (Puma concolor) were associated significantly and positively and significantly and negatively, respectively, with the presence and prominence of utilities. Woodrats were also negatively associated with the presence of horses. Raccoons (Procyon lotor) and coyotes (Canis latrans) were associated significantly and negatively and significantly and positively, respectively, with plant bulk and permanence. Cougars and gray foxes (Urocyon cinereoargenteus) were negatively associated with the presence of roads. Roadrunners (Geococcyx californianus) were positively associated with litter. The only species that had no significant correlations with any of the environmental variables were black‐tailed jackrabbits (Lepus californicus) and mule deer (Odocoileus hemionus). Bobcat tracks were observed more often than gray foxes in the study area and bobcats correlated significantly only with water availability, contrasting with results from other studies. Our results appear to indicate that maintenance of habitat fragments in urban areas is of conservation benefit to some animal species, despite human activity and disturbance, as long as the fragments are large.

城市规划与城市可持续发展

城市可持续发展是人类全面实施可持续发展战略的一个重要方面,它有其特定的内涵。城市规划是实施城市可持续发展战略的有效工具,在城市规划中引入可持续发展理论是引导城市可持续发展的重要一环。以可持续发展为原则的城市规划应突出其未来导向性、环境导向性、社会导向性的特点,文章就其含义及实现途径进行了分析和探讨。     

土壤学与广东持续农业的发展

持续农业是关于建立资源、生态、地力、经济效益等各个方面均可持续发展的农业制度的一种思想．水土流失、土地退化、耕地锐减、环境污染，制约着广东农业的持续发展．土壤学应围绕持续农业开展研究工作．目前应加强土壤生态环境的保护，防治土地退化，提高土壤肥力，保证耕地生产力的持续发展．应开展土壤资源的动态变化研究，为合理开发和利用土壤资源提供科学依据．     

战略环境评价（SEA）和可持续发展

SEA的作用不仅仅在于将EIA（环境影响评价）扩展到更具战略意义的决策层,它还是迈向可持续发展的关键一步,它有助于从政策到计划、规划吧至最后的项目遵循可持续发展目标,SEA是联系目前正在进行的项目EIA和使人类活动达到维持环境质量这一目标的纽带,文章讨论了SEA开展的必要性,介绍了SEA的2种类型,结合英国开展的实例,论述了“遵循型”SEA的主要内容及其应用前景。
