Based on the example of shahe reservoir, the text makes an analysis on circulation, management and environment and social economy development condition of the surrounding ecosystem. Then, the author carries on inquisition, data analysis and summary and makes calculation and demonstration of the safe stability of the dam ,and discusses the risking obviation and reinforcing technique. Finally, based on the existing research of sustainable development, experts" opinions and Mathematical Statistics analysis, the author brought forward an indication system suitable for reservoirs" sustainable development This system is made up of 4 first class indexes, 13 second class indexes, 38 foundational indexes. The 4 first class indexes are the dam safety evaluating index, the management index of reservoirs, the water ecosystem system stability index, the reservoirs construction effect index. The 13 second class indexes are the construction quality evaluating index, the dam running and management evaluating index, the flood control standard recheck index, the structure safety evaluating index, the anti- earthquake evaluating index, seepage safety evaluation index sign, the metal structure safety evaluating index, the engineering facility index, the management index, the water ecosystem system stability index, engineering effect index, the economic development index, the society development index.

本文以沙河水库为例，对其运行、管理及周围生态环境和社会经济发展状况进行调查，并将调查资料进行分析、归纳、总结；然后对水库大坝的安全稳定情况作出了简要的计算和论证，并讨论了水库的主要除险加固技术；最后在总结现有可持续发展研究的基础上，征集专家的意见，进行数理统计分析，提出了由4个一级指标、13个二级指标、38个基层指标组成的一套适合该水库可持续发展的指标体系。4个一级指标分别为：水库大坝运行安全综合评价指标、水库管理指标、水资源生态系统稳定性指标、水库建设效应指标；13个二级指标分别为：工程质量评价指标、大坝运行管理评价指标、防洪标准复核指标、结构安全评价指标、抗震安全评价指标、渗流安全评价指标、金属结构安全评价指标、工程设施指标、管理指标、水资源生态系统稳定性指标、工程效应指标、经济发展指标、社会发展指标。

Based on the fact that it lacks of quantification about the theory at present, this paper puts forward the new idea about mechanism of system coupling using emergy method in the ecotone between agriculture and pasture in North China as an example, where has serious dilemma of economical and ecological.

以农牧交错带为例，针对在生态经济系统目前该理论的定量化方面研究不足的事实，提出用能值方法考虑农牧交错带系统耦合的机制，并指出农牧交错带系统耦合机制应建立在土地利用方式、子系统间能值转化过程和生态系统的能值储备上；同时影响系统耦合机制的主要因素有初级生产力的大小、畜牧业的内部结构和畜牧业的发展规模以及生态系统服务价值的大小。

The first is that the natural landscape has not the strong appeal to the tourists. The second is the shelter-forest in the seacoast has been destroyed seriously, it is difficult to recover the ecological system. The third is the construction of the infrastructure is needed badly. The fourth is because of the low living standard of the local residents; the improvement needs to be considered. The development should be done in stages.

除具备生态环境良好等开发生态旅游业的有利条件外，还必须重视所存在的不利条件：一是现有自然景点尚未对游客产生巨大的吸引力；二是陵水县的海岸带防护林已遭到较严重的破坏，生态建设的任务很重；三是需加强对水、电等基础设施的建设，建设力度较大；四是当地居民的生活水平不高，在开发中还应适当考虑提高居民的生活水平。

Because the area is not wide, the leading industry is characterized by projects of development. The construction of the Eco-area is very important in the regional development. The Eco-area should achieve the following objectives. 1 Has perfect shelter-forest in the seacoast, clean sea beach and the greenbelt area accounting for more 50% of the total area. 2 Has the system of collection and disposal of rubbish, the system to make economize use of water. 3 In agriculture, try best to use little chemist. 4 makes the ecological the theme; lays down regulations on the tourism, cultural knowledge spreading and bodybuilding. But we should pay more attention to the disadvantages.

由于所涉及的区域面积不大，主导产业主要以开发项目的形式表现出来，生态旅游度假区建设项目是生态旅游业发展的主要环节，应达到如下标准：一是有完善的海岸带防护林，清洁的海滩，生活及活动区的绿化面积达到50%以上；二是区域内建有完善的生活垃圾收集、处理系统，节水设施和稳定塘污水处理系统；三是农业以绿色产品为标准，栽培、管理、贮藏加工过程都尽可能减少对农用化学品的使用；四是以生态为主线，建成含旅游活动、科普宣传、饮食文化和健身休闲等为内容的设施和综合管理规章。

The eco-tourism as a traveling and sightseeing of caring environment ,under the situation of not disturbing the natural region, protecting ecological environment, reducing the negative influence of traveling and providing beneficial social and economic activities situation to the local people, mainly through protection of environment, achieves the goal local ecology and population can develop sostenuto.

不同区域的湿地公园其恢复和重建的核心生态服务功能应在科学分析研究的基础上因地制宜地确定，例如：城市建成区域中建设的湿地公园应以水质净化和调节改善小气候为恢复和重建的核心生态服务功能；城郊的湿地公园应以水质水源保护和生物多样性保育为恢复和重建的核心生态服务功能等等。

The 54 accessions were classified into five major groups:Ⅰ,Ⅱ,Ⅲ,Ⅳ and Ⅴ by cluster analysis using UPGMA, which showed significant relationship with the origin regions of accessions. Genetic differentiation between and within eight eco-geographical groups of C.dactylon was estimated by Shannon's diversity index, which showed that 63.81% genetic variance existed within group, and 36.19 % genetic variance was among groups, indicating rather large genetic distances among those germplasm, and there was a correlation between genetic differentiation and eco-geographical habits among the groups.

聚类分析结果表明，52份材料可聚为5类；基于Shannon多样性指数估算了8个狗牙根生态地理类群内和类群间的遗传分化，类群内的遗传变异占总变异的63.81%，类群间的遗传变异占总变异的36.19%，表明这些抗源材料遗传差异较大，各生态地理类群间的遗传分化与其所处的生态地理环境具有一定的相关性。
