平顶山市卫东区地矿局打非治违首战告捷

<正>7月11日,平顶山市卫东区政府牵头,卫东区地矿局联合相关部门组成300余人的执法队伍,出重拳、下猛药,一举荡平了为害该区7年之久的蒲城任寨非法采砂点,首战告捷。据了解,任寨非法采砂点地处任寨村与门楼张村结合部。2008年,当事人任某某开始在其责任田内非法采砂。多年来他不断扩大规模,逐步把采砂范围延伸至邻村门楼张村大片林地内。由于年长月久,采砂量巨大,门楼张村林地、树木被其毁坏殆尽,

污泥–生活垃圾混合填埋体的压实特性研究

在垃圾填埋场混合填埋污泥是污泥处置途径之一。针对混合填埋体的干密度参数对填埋场的强度和稳定性有重要影响,开展了不同击实功和不同污泥添加量条件下混合填埋体的击实试验,研究压实特性。结果表明,在不同击实功和不同污泥添加量条件下混合填埋体相比垃圾的干密度增加了2.74%~32.50%,改善了垃圾的压实特性;混合填埋体的干密度随着击实功的增加而增大,可以用一个双曲线模型描述。对模型参数的物理意义进行分析,讨论模型参数的变化规律,给出模型参数的取值范围,?值在0.373~0.750之间,?值在1.958~2.158之间;混合填埋体的干密度随着污泥添加量的增加而增加,满足对数模型。讨论模型参数的变化规律,给出模型参数的取值范围,b值在0.331~0.776之间,c值在0.052~0.164之间。综合运用两个模型可以预测混合填埋体的干密度参数,减少试验的工作量,为填埋场的设计分析提供理论依据。分析混合填埋体击实评价方法及机理,提出依据混合填埋体干密度的变化趋势判断是否击实。     

黑河流域干旱生态系统红砂荒漠空间斑块结构及其生态适应策略（英文）

In many arid ecosystems,vegetation frequently occurs in high-cover patches interspersed in a matrix of low plant cover.However,theoretical explanations for shrub patch pattern dynamics along climate gradients remain unclear on a large scale.This context aimed to assess the variance of the Reaumuria soongorica patch structure along the precipitation gradient and the factors that affect patch structure formation in the middle and lower Heihe River Basin(HRB).Field investigations on vegetation patterns and heterogeneity in soil properties were conducted during 2014 and 2015.The results showed that patch height,size and plant-to-patch distance were smaller in high precipitation habitats than in low precipitation sites.Climate,soil and vegetation explained 82.5% of the variance in patch structure.Spatially,R.soongorica shifted from a clumped to a random pattern on the landscape towards the MAP gradient,and heterogeneity in the surface soil properties(the ratio of biological soil crust(BSC) to bare gravels(BG)) determined the R.soongorica population distribution pattern in the middle and lower HRB.A conceptual model,which integrated water availability and plant facilitation and competition effects,was revealed that R.soongorica changed from a flexible water use strategy in high precipitation regions to a consistent water use strategy in low precipitation areas.Our study provides a comprehensive quantification of the variance in shrub patch structure along a precipitation gradient and may improve our understanding of vegetation pattern dynamics in the Gobi Desert under future climate change.     

植被动态控制黑河流域典型生态系统能量分配——观测及数值模拟（英文）

Understanding the controls on seasonal variation of energy partitioning and separation between canopy and soil surface are important for qualifying the vegetation feedback to climate system.Using observed day-to-day variations of energy balance components including net radiation,sensible heat flux,latent heat flux ground heat flux,and meteorological variables combined with an energy-balanced two-source model,energy partitioning were investigated at six sites in Heihe River Basin from 2014 to 2016.Bowen ratio(β) among the six sites exhibited significant seasonal variations while showed smaller inter-annual fluctuations.All ecosystems exhibit a "U-shaped" pattern,characterized by smaller value of β in growing season,with a minimum value in July,and fluctuating day to day.During the growing season,average Bowen ratio was the highest for the alpine swamp meadow(0.60 ± 0.30),followed by the desert riparian forest Populus euphratica(0.47 ± 0.72),the alpine desert(0.46 ± 0.10),the Tamarix ramosissima desert riparian shrub ecosystem(0.33 ± 0.57),alpine meadow ecosystem(0.32 ± 0.17),and cropland ecosystem(0.27 ± 0.46).The agreement of Bowen ratio between simulated and observed values demonstrated that the two-source model is a promising tool for energy partitioning and separation between canopy and soil surface.The importance of biophysical control explains the convergence of seasonal and annual patterns of Bowen ratio for all ecosystems,and the changes in Bowen ratio showed divergence among varied ecosystems because of different physiological responses to energy flow pathways between canopy and soil surface.     

小麦越冬冻害的后效及分级

受冻麦苗发育推迟,株高降低,穗粒数增加,千粒重下降,亩穗数减少.受冻麦田减产程度主要受亩穗数减少影响.死茎率、亩穗数、亩产量与死株率呈极显著相关.故用死株率把麦田冻害程度分为4级.
