野生动物学报, 1990 鸟类是人类的朋友,是我国宝贵的自然资源,它们都会给人类带来益处。它们还以优美动人的姿态、婉转嘹亮的歌声、绚丽多彩的羽毛给大自然带来了生机,也给人们的精神生活增添了无限的情趣。为了保护珍贵鸟类,维护自然生态平衡和人类永续地利用自然资源,于1981年国务院颁布了关于加强保护鸟类,开展全国性的“爱鸟周”活动的决定。在这个决定的指引下,全国各级政府,各级林业主管部门和各级野生动物保护协会,几年来在宣传贯彻国家的政策、法规及保护鸟类方面做了大量的工作,采取了一些有利措施,全国各省市和一些地区,在“爱鸟周 ...

Conservation Biology, EarlyView.Abstract Protected areas cannot halt biodiversity loss in isolation; integrating them with surrounding human‐dominated landscapes is critical. However, this integration is challenged by substantial landscape heterogeneity at protected area borders, making it difficult to determine cross‐border changes in ecosystem service provision.

, 2009 区域人类活动是生态系统演变发展的重要驱动因子,定量评价区域人类活动强度是分析区域人类活动对生态系统影响的基础。本文提出了一套将区域人类活动强度定量化的方法:首先,通过选取人口密度、经济密度、人均国民生产总值、农业产值和普通中学在校中学生数等17个代表性指标,构建了在社会、经济和文化三方面反映区域人类活动强度的评价指标体系;然后,采用层次分析法获取各指标的权重;最后,利用加权法将各指标综合获取区域人类活动定量化指数。将本方法应用于中国武川县、蒙古达尔汗乌拉省和俄罗斯扎卡缅斯克地区,并验证了其有效性。经计算,

AI foundation models in plant biology
New Phytologist, EarlyView.Foundation models decode genomes, engineer proteins, phenotype crops, and drive AI agents across plant biology. This figure was created in BioRender (BioRender.com/xcmmkel). Summary Rapid technological progress has enabled plant biologists to accumulate unprecedented volumes of multi‐scale, multi‐modal data, yet this abundance of data has intensified ...

Risk, Hazards &Crisis in Public Policy, Volume 17, Issue 4, December 2026.ABSTRACT Public communication campaigns on environmental issues rely on economic and ecological arguments, assuming that the recognition of messages is sufficient to produce adjustments in practices. Drought constitutes a specific case of this problem, as a creeping crisis: a slow‐onset hazard whose effects remain weakly visible in everyday life.

Shuitu Baochi Xuebao, 2003 黄土高原全新世以来可划分出5个侵蚀阶段,其起始年龄分别为11,7.0,0.7,0.3,0.15kaBP。根据高原现代河流沉积物的粒度组成、河流输沙量、径流量和年降水量等数据建立了各个指标的回归方程。根据各方程和全新世不同时期阶地沉积物的实测数据,计算了各个阶段的平均古侵蚀强度和流域输沙量。结果表明,不同时期水土流失的主要控制因素是不同的:在11000～7000aBP时期以构造活动因素为主,在7000～2000aBP期间以气候因素为主,在2000～700aBP和300aBP以来以人为活动因素为主 ...
