The scheme embraces four projects , namely ( 1 ) to build up sluices at anqiu bridge and nanzhou bridge ( and the one at anqiu bridge is the first choice ) so that pollutants can be from entering the lake ; 2 ) as a necessary accessory for the above project , to supplement water capacity from changdang lake as a strategic water source into the protection program , and culvert - pipe plan is recommended from two other alternatives through systematic analysis ; 3 ) to carry out comprehensive realignment for some reed regions which are located at the entrances of the lake , and to develop a wetland ecosystem mainly with some reeds ; and 4 ) to set up a green protection belt right round the lake , including planting reeds at lakebeach , building forest belt , developing bases of green foodstuff and disposing sludges in the lake base 该方案由4个工程子系统组成， ( 1 )截污工程：在岸丘桥和南州桥位置各筑一节制闸(而岸丘桥工程又是首选工程) ，以封住湖泊两头入流，杜绝污染物进入水源地的截污工程； ( 2 )引水工程：是截污工程的配套工程，利用下游长荡湖来补充水量，并对3个引水工程设想进行了系统分析，推荐涵管方案，同时将长荡湖作为该市战略水源地一并纳入保护体系中； ( 3 )湿地生态处理工程：对进入荡区前的芦苇区进行综合整治，发展以芦苇为主的湿地生态处理工程； ( 4 )环湖绿色自然保护带工程：包括建设围湖芦苇荡、环湖林带、绿色食品基地以及污泥处置。
The paper studies composition of grasshopper community in different habitats , found that differences in family , genus and species and analyzed the causes of those . the author analyzed the following aspects by spss software and the measure of euclidean distance : ( 1 ) analyzed the relationship between grasshopper species and geographical distribution and divided 9 forestry belt into 3 main habitat model : low mountain conifer and broadleaf integrated forestry belt ; low mountain chanbai conifer forestry belt and middle - high conifer - betula ermam / - tundra belt ; adopted sum of deviation of square to clustered ecological species groups , and thus divided 48 grasshopper species into 3 main category , 12 ecological species groups 在长白山地区蝗虫生态分布特点的研究中，主要应用spss软件包、采用euclideandistance测度法对以下两方面内容进行了分析： ( 1 )对长白山地区蝗虫地理分布关系进行了分析，将长白山9个林带划分为三大生境型：低山针阔叶混交林带、低山长白松林带和中高山针叶?岳桦?苔原复合体； ( 2 )利用离差平方和法对生态种组进行等级聚类，结合实地调查结果，将48种蝗虫划分为三大类12个生态种组。
The construction must suit measures to local conditions and also take measures suited to local problems , some tree species should be taken as the main bodies of this construction , then dispose shrub and grasses in order to increase the quality of afforestation effects as well as set up a steady long term urban eco - forest system . in accordance with the serious air pollution situation and so on in the city area , the protection tree walls around the parts of polluting source and the sand - break forest belts and water and soil protection forest belts etc . would be built 绿化的核心是要因地制宜，因害设防，以乔木为主体，乔、灌、草、花相配置，提高“绿质” ；建立和期稳定的绿地生态体系，针对市区污染状况建立区域防护隔离林带、防风固沙林带、水土保持林带等，形成城市绿化、园林公园、森林绿地所组成的生态格局。
On the foundation of theoretical analysis , this paper combines the condition of economic and nature of baoding hebei province to concept the landscape ecological program frame . in order to vague the limit of city center and village . the main planning idea is to establish a central ecological forest x - axis and eastern wetly tourist landscape district as well as water network and traffic line landscape ecosystem for the open town and country ecology system 在理论分析的基础上，本文结合保定市的自然、经济状况，构想了保定市景观生态规划框架，规划目的是模糊城市中心与乡村的界限，构想建立一个以西部绿色屏障林带、中部特色农业带和景观城市带为中心的生态纵轴、东部湿地旅游景观区以及环形河网和交通线为横轴的开放式的城乡融合景观生态系统。
Argentina , for whom carlos tevez was making a lively contribution to his second start of germany 2006 , forced their first and only half - chance of the opening 45 when marauding left - back juan pablo sorin burst through on to a tevez nutmeg and was only prevented from teeing up hernan crespo for the opener by a timely interception from per mertesacker 第19分钟：在本届世界杯上第二次首发出场的卡洛斯?特维斯表现非常活跃，他为阿根廷队赢得了在上半场第一次也是唯一一次的机会：上前助攻的左后卫胡安?索林带球突破，随后将球交给了特维斯，然而佩尔?佩尔?默特萨克及时的拦截化解了赫尔南?克雷斯波的进攻。
Afterward wood 2h reduce lower 33 . 7 % than toward wood , 11 . 4 % afterward wood 1 oh , which is distinct . in higher wind speed afterward wood 1 oh is not distinct , which indicate the distance of protecting forest is no more than 10 h . 5 together with the ecological benefit of returning cultivated to woodland and grassland engineer of bashang , economical benefit must be considered to succeed in the ecological construction 4林带对风速减缓效果研究表明，较小风速下，林带对风速的减缓效果明显，林后2h处风速比林前平均降低了33 . 7 ，林后10h降低了11 . 4 ，与林前风速有显著差异；较大风速下，林后10处风速与林前差异不显著，表明防护林的防护距离小于10h 。
