我国大部分自然保护区进行了旅游开发,为自然保护区的发展带来了生机和活力。但是由于缺乏可持续发展思路,缺少科学管理经验,自然保护区内的旅游业在产生社会、经济利益的同时也产生与保护生态环境背道而驰的不良后果。 相似文献

This article explores the relationship between ecofeminism, food, and the philosophy of place. Using as example my own neighborhood in a racially integrated area of Philadelphia with a thriving local foods movement that nonetheless is nearly exclusively white and in which women are the invisible majority of purchasers, farmers, and preparers, the article examines what ecofeminism contributes to the discussion of racial, gendered, classed discrepancies regarding who does and does not participate in practices of locavorism and the local foods movement more broadly. Ecofeminism, it is argued here, with its focus on the ways that race, class, gender, and place are ontologically entangled, helps to highlight the ways identity and society are made and re-made through our encounters with food. 相似文献

In the Discussion, Nash et al. (2019) estimate the seasonal change in groundwater volume for a portion of the restored Sierra Nevada Meadow that we evaluated (Hunt et al. 2018) and use this estimate as an upper bound on the possible contribution to flow that is attributable to restoration. The authors conclude that raising the channel bed elevation and reconnecting the meadow floodplain most likely reduced summer streamflow. In contrast, we report at least a fivefold increase in baseflow from the meadow in the years following restoration. In addition, we observed that, after restoration, the previously intermittent stream below the meadow flowed continuously throughout the summer months, despite record drought conditions, and in 2015, the lowest snowpack on record. We suggest that the groundwater budget presented in the Discussion may not adequately represent conditions within the meadow because the authors extrapolate from 5 near‐channel groundwater wells across 62 ha of meadow and assume an area of influence that is approximately one‐sixth of the meadow area. We conclude that the conversion of an intermittent stream to perennial flow during drought conditions is a stronger check on our gauge data than the groundwater budget presented in the Discussion. 相似文献
