Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Root exudates play a key role as signals and nutrients in mediating plant–microbe communication. However, critical knowledge gaps remain regarding how root exudates mediate soil–microbe–plant interactions to regulate crop yield under long‐term straw mulching combined ...

Coastal reclamation impacts on carbon storage in China’s coastal wetland [PDF]
, 2017 滨海湿地具有较高的初级生产力和较缓慢的有机质降解速率，是缓解全球变暖的有效碳汇，得到全球学术界的广泛关注。近年来由于人口增长和沿海城市的快速发展，海岸带地区围填海活动呈加剧趋势，导致滨海湿地的急剧退化。开展围填海活动对滨海湿地碳储量造成影响的研究，对我国海岸带围填海活动的优化管理、制定滨海湿地保护行动计划以及减缓气候变化的战略决策具有非常重要的学术价值和现实意义。 本论文以全国围填海区内的滨海湿地作为研究对象，基于全国围填海土地利用分类数据、滨海湿地和沿海自然保护区空间分布数据以及文献检索碳密度数据 ...

Measuring and Mapping the Impact of Land Use and Land Cover Change on the Hydropower Production——A Case Study of Jiulong River in Fujian Province [PDF]
, 2017 水电是全球利用最广泛的可更新能源,其生产能力对土地利用/覆被的变化非常敏感。研究土地利用/覆被变化与流域水电生产的数量、价值及其空间分布的关系是流域水资源规划和管理的基础。本论文应用InVEST模型评估九龙江流域土地利用/覆被变化对水电生产数量及其价值的影响。结果表明：2000~2010年间,九龙江流域内,土地利用/覆被主要由蒸散量较大的耕地和林地转化为蒸散量较小的建设用地,产水量增加了0.66%。但由于耕地和建设用地的耗水量较其他土地利用/覆被类型大,水电生产的供水量却降低了8.46 ...

When and why to give shorebirds a head start
Conservation Biology, EarlyView.Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

耦合生态系统服务供求关系的生态安全格局动态分析——以闽三角城市群为例 [PDF]
, 2018 实现分区管理是缓解城市群生态安全空间差异的有利途径。基于供求理论构建了生态系统服务供求关系动态模型框架,并利用供给与需求的象限区划表征闽三角城市群生态安全格局;在不同的尺度变换上,运用价值单量修正模型、INVEST生境质量模型、景观指数模型、生态韧性模型、熵权法等方法综合测度城市群生态系统服务供求水平,实现生态安全格局的分区化;引入环境库兹涅茨曲线理论解析区域生态安全格局现状和成因;数据分析借助Arc GIS可视化表示。研究发现:(1)闽三角城市群存在50%区域属于生态安全高供给失衡区,其中70 ...
