Practice and Reflection on Strengthening Grassroots Party Building Work in Agricultural Research Institutes:A Case Study of Changli Pomology Institute,Hebei Academy of Agricultural and Forestry Sciences

Changli Pomology Institute,Hebei Academy of Agricultural and Forestry Sciences is taken as the research object.Starting from the relationship between party building and scientific research,in response to the problems in grassroots party building in agricultural research institutes such as insufficient theoretical learning,single party building activity mode,and lack of incentive mechanism in party affairs work,the"three integrations"approach and"four integrations"model are proposed to strengthen the deep integration of party building and scientific research in provincial-level agricultural research institutes.The"three integrations"approach is the integrated development of party building and scientific and technological innovation,the integrated development of party building and scientific and technological services,and the integrated development of party building and technology talents.The"four integrations"model includes the implementation of party building innovation projects,the implementation of 1+N branch pairing and co-construction,the implementation of the"party building+"work method,and the implementation of"theme intersection"activities.The research aims to promote the deep integration of party building and scientific research in provincial-level agricultural research institutes.

Observations of coastal aeolian dune movements at Feicuidao, on the Changli Gold Coast in Hebei Province

High-precision RTK GPS technology was used to survey the movements of typical coastal dunes, including a coastal crescent dune and a coastal transverse ridge, in the Feicuidao region of the Changli Gold Coast in Hebei Province in 2006-2008. Our data provide information on the direction, type, and velocity of coastal dune movements, and indicate that the coastal dunes in this re- gion are characterized as slow and landward advancing, with to-and-fro fluctuations. The bottom of the studied coastal transverse ridge was stable during the observation period but the position of its crest advanced eastward （seaward） during summer and au- tumn, and moved landward （westward） in winter and spring. Thus, its crest moved generally landward （westward） but fluctuated to-and-fro eastward and westward. In contrast, the entire coastal crescent dune advanced landward （westward） in a to-and-fro manner, and the velocity of its movement was faster than that of the transverse ridge dune. These results are mainly related to the wind conditions in the research area, the height and volume of the two types of coastal dunes.

Community characteristics of macrobenthos community in Changli Gold Coast National Nature Reserve of Hebei in China

Macrobenthic communities in the surrounding waters of Changli were investigated during spring and summer in2016.Differences in species quantity,abundance and biomass,the dominant species and species diversity index of macrobenthos were analyzed.The results showed that58macrobenthos species were identified in spring,and92macrobenthos species were identified in summer.The composition of dominant species seasonally varied;however,most of them were species belonging to Polychaeta.The abundance of macrobenthos in summer was slightly higher than that in spring,while the biomass in summer was significantly smaller than that in spring.Bray-Curtis cluster analysis and multi-dimentional scaling(MDS)analysis indicated that macrobenthic communities were divided into three communities in spring,and two in summer.The abundance-biomass comparison(ABC)curve method was used to monitor the disturbance of environmental pollution for macrobenthic community.The results showed that the macrobenthos in this area received serious disturbance from environmental pollution.

COMPREHENSMIVE PLANNING FOR WATER RESOURCES EXPLOITATION AND WATER POLLUTION CONTROL FOR CHANGLI COUNTY--A CASE STUDY FOR SMALL TOWNS OF CHINA

One of the major characteristics about the water resources and water pollution in China is that the southem part of the country is endowed with abundant water resources with serious water pollution occurring in some areas, whereas the northem part is endowed with limited water resources with relatively more serious water pollution existing in some areas. Urban areas have been mainiy affected by point source pollution while ecological damage is most serious in rural areas and small towns. With rapid development of socio-ecomony and urbanization, many new small towns have occurred in China, and the concemed ecological problems such as water pollution and soil erosion have been gradually changed into local point source pollution. Water envirormental problems are geding more and more serious. To resolve the above mentioned problems and to provide a mode for towns in North China, the Research Center of Water Problems of Chinese Academy of Sciences undertook the research project of comprehensive planning of urban environment of Changli County, Hebei Province. Conceming the limited financial strength of the county and its relatively low level of socio-economic development, the planning is aimed to protect and to improve Changli's environment with the least cost, to promote the suitable development of socio-economy of Changli County, and to carry out effective environmental regulations, control and managemeat.

河北昌黎县主要入海口水体与沉积物中重金属污染分析

为加强河北昌黎县近海水体环境保护和管理,在其境内主要入海口分别采集水样及表层沉积物,分析Cd、Pb、Cu等8种重金属含量,并采用单因子指数法、地积累指数法和潜在生态污染指数法对其重金属污染状况和风险进行评价。结果表明:8种重金属在3个入海口水体中的浓度大小顺序不尽相同,新开口重金属含量顺序为Ni>Cr>As>Pb>Zn>Cu>Hg>Cd,大蒲河口为Ni>As>Cr>Pb>Zn>Cu>Hg>Cd,东沙河口为Ni>Cr>As>Zn>Pb>Cd>Hg>Cu。8种重金属在各入海口含量差异较大,Ni含量最高,与《海水水质标准》(GB 3097—1997)中第二类水质标准限值作对比,3个入海口Ni含量均达到重度污染。Pb在新开口达到重度污染,在大蒲河口为轻度污染,东沙河口未超标。Cr在新开口为轻度污染。Cd、Hg、Cu、Zn、As均未出现污染。在沉积物中检出的重金属中Cd在3个入海口均处于偏中度污染水平,潜在生态风险系数新开口、大蒲河口和东沙河口分别为160.71、171.43、150.00,分别达到高度风险、高度风险和偏高度风险。重金属Cu和Ni在大蒲河口和东沙河口、Pb在新开口均出现轻度污染。潜在生态风险综合指数显示,新开口、大蒲河口和东沙河口均属于中度风险。从重金属贡献率来看,以Cd的贡献率为最大,需引起足够的重视。

昌黎井数字化水位观测同震效应分析

通过整理昌黎井水位观测在2005年3月29日至2015年12月31日期间记录到的19个强远震(M≥7.0)和2个近区中等地震(300 km以内M≥4.0),从空间分布、地震参数方面进行了统计,分析了水位同震变化特征及其机理。结果显示:①不论强远震还是近区中等地震,在该井产生的水位同震变化只有两种形态:一是振荡型,二是脉冲(或振荡)—持续上升型,且第二种变化常伴随着同井水温同步上升变化;②产生脉冲(或振荡)—持续上升型同震变化的强远震空间位置具有方向性,且一般M≥8.0,震级和震中距与阶变幅度呈很好的幂函数关系;③含水层对地震波的弹性响应是引起振荡型变化的主要原因,昌黎井具有良好的地质构造环境,同时发生强震时井-含水层系统应力(能量密度)增强显著,含水层渗透性随之增强,M 2波潮汐因子和相位差在地震前后均发生异常变化,这可能是导致水位阶变上升的原因,再依据同井水温探头位置处于正梯度变化层,水位上升水温也随之上升,这是产生水位、水温同时上升的主要原因。

区位和管理政策对海岸带土地利用变化的影响——以昌黎黄金海岸地区为例

本文在RS和GIS支持下研究了河北昌黎黄金海岸地区1985年至2000年的土地利用变化格局及其影响因子。该区域的海岸区位对海岸带土地利用变化具有重要影响作用,近岸带变化较剧烈,远岸带变化较小,且具有不同的变化特点。海岸带管理政策对土地利用变化的程度和特征存在重要影响,开发区土地利用变化较剧烈,其变化类型受开发方式及其目标影响;保护区主要是大片沙丘转变为林地和草地。

昌黎井水温潮汐形成机理分析

昌黎井水温具有潮汐变化特征,并且与该井水位的潮汐动态同步。该文对比分析了井水温潮汐特征产生的可能原因。认为井水温潮汐现象在井管内任何深度不一定都有反映,能够显示温度潮汐周期性变化大体有两种模式:一是井管水体具有足够大的温度梯度,水体上下周期性运动时,温度探头可以捕捉到水体的温度变化;二是井-含水层系统地下水交换量的多寡引起水温同步的周期性变化。研究结果表明,昌黎井水温潮汐现象是次生效应,水温潮汐动态与井孔管路特殊结构有一定关系。
