5月29日,生态环境部举行5月例行新闻发布会,生态环境监测司司长柏仇勇,中国环境监测总站副站长刘廷良出席发布会,柏仇勇介绍了生态环境监测改革工作进展和2018全国生态环境状况。生态环境部新闻发言人刘友宾主持发布会,通报近期生态环境保护重点工作进展,并共同回答了记者关注的
因为泥炭沼泽单位面积的碳储量高,所以其对减缓气候变化具有重要意义。在中国,开展全国性的泥炭沼泽调查起步较晚,构建泥炭沼泽碳库调查技术体系十分紧迫和必要。根据《联合国气候变化框架公约》对"不小于1 hm~2湿地的排水和复湿"操作系统的相关规定,从调查技术路线、调查斑块区划、泥炭沼泽边界范围的界定、调查内容指标、植物样方和土壤采样点设置、生物量调查、土壤调查、样品处理等方面,构建泥炭沼泽碳库调查和监测
丹霞地貌是一种常见的地貌类型,在中国境内分布广泛。陕北丹霞地貌分布在中国西北半干旱-干旱地区,在成因演化、历史人文、旅游开发等方面具有较高的研究利用价值,因此,有关部门应重视保护陕北丹霞地貌工作。
The response of soil fauna to the litter decomposition process has received considerable attention, but this effect has not been fully examined in agroforestry systems. A 1-year in situ decomposition
The aim of this study is to determine the influence of tree litters on soil nutrients in a managed forest in southwestern Nigeria. Mono species tree clusters consisted of indigenous species: Gmelina a
Climate change is predicted to alter global precipitation regimes.However,the response of soil carbon and nitrogen cycles and soil microorganisms to precipitation reduction is poorly understood but is
基于"地貌学"课程的重要性及其现存教学方式的不足,提出进行以应用为导向的地貌学教学尝试,并以《滑坡崩塌泥石流灾害详细调查规范》《建筑边坡工程技术规范》等为例进行应用示范。
Due to the Tibetan Plateaus unique high altitude and low temperature climate conditions,the regions alpine steppe ecosystem is highly fragile and is suffering from severe degradation under the stress
伴随大数据时代的来临,科学研究数据及其成果再应用的重要性日益显著,而如何量化评价数据的重要作用和价值以及数据贡献者对科学的贡献显得尤为迫切。然而,目前对这方面的研究尚处于起步阶段。本文基于全球变化暨地球科学2014–2018年发表的数据集,开展"数据影响力积分"分区的计量方法研究,提出科学研究数据对科学影响力的不同类别计量评估体系。以规范性引文为基础,以引用数据的发表论文期刊影响因子为权重,利用年
The present study area involves part of a deformed coalesced fan located along the Himalayan Frontal Thrust(HFT) on the east of river Tista near the India-Bhutan border. The area is marked by two spec
