In this paper , the data are dealt with mathmatica which has better calculation , so , the sustainable ability dependence and the trend of each index is obtained . the result is : the sustainable capacity of the water resource complex system is lower , belonging to inferior stage of sustainable development ; the sustainable capacity of the water resource system itself is worse ; the coordination level between water resource system and social - economical system is better ; but , the coordination level between water resource system and environment is worse . the key factor influencing the water resource system sustainable utilization of guanzhong region is water resource itself and the environment 论文选用计算功能较好的mathmatica软件处理数据，得出关中地区水资源可持续利用评价指标体系中各层指标的可持续隶属状况以及它的发展趋势，结果表明，关中地区水资源复合系统整体的可持续发展能力普遍较低，处于可持续发展的弱势阶段，其中水资源系统本身的可持续发展能力较弱，水资源系统与社会经济系统的协调状况较好，而水资源系统与环境系统的协调状况较差，指出影响关中地区水资源可持续利用的关键因素在于水资源本身和环境。
This viewpoint also was realized and proved in china since the start of the reform and opening - up , especially , in the accelerating process of integration of world economy , therefore , it is absolutely necessary to put the emphasis on this problem in our research . the papers aim to find out the strategic approach , which will work steadily in a long term 我们使用的方法论是系统动力学，它被广泛运用于社会经济系统的研究，取得一系列重大成果，被誉为“社会科学的实验室” ，它能处理诸如营销系统等多变量、高阶、多环节的复杂系统，对之进行动态仿真，并能进行政策试验、政策寻优。
The traditional ahp processing data is the so - called " point " data or " rigidity " data . however , the real social economic system is a flexible system , the studying issue is also a flexible issue , so describing this kind of issue by the traditional mathematics " method may not be effective . therefore , the mentioned ahp is a decision - making judgment under this circumstance 传统ahp处理的数据是“点”数据或称“刚性”数据，而现实的社会经济系统则是柔性系统，所研究的问题是柔性问题，用传统的数学方法描述未必有效，灰色层次分析法就是针对这种情况提出的一种决策方法。
Depending on stratagem of continuable development , development programming of states or regions should go in for correspond development of nature , human being , society and economy , to be brief , correspond development of multi - object , so perfect means of resolving the settle of problems is to establish multi - object optimization models restricted by dynamic input - output equation 社会经济系统是一个复杂的动态大系统，在可持续发展战略指导下，一个国家和地区的发展规划应追求的是自然、人、社会、经济的协调发展，即多个目标的协调发展。因此，建立一个以动态投入产出方程为核心约束的多目标优化模型成为解决此类问题的理想方法。
The results indicate that when the population , economic and urban scales approach or exceed the water resources carrying capacity , or the utilization of water resources approaches or exceeds the threshold of natural water resources , the water resources system significantly slows down the development of socio - economic systems , including the urbanization process 研究成果指出，当人口、经济及都市规模接近或超过水资源饱和，又或者都市化水资源接近或超过自然水资源的范围，水资源系统明显使社会经济系统发展缓慢下来? ?也包括都市化的过程。
On the basis of the current situation of natural ecological system and social economy system in huludao , i . e . according to the current situation of huludao urban plan and urban landscape and urban air pollution , point out the correct way about huludao development is to build ecopolis and sustainable development , at the same time , point out that adjusting urban distribution , enlarge the scope of urban landscape , improve the urban eco - environment . in the end , make huludao city to come up to the standards of ecopolis 依据葫芦岛市自然生态系统和社会经济系统的现状，即根据葫芦岛市城市规划现状、城市园林绿地现状和城市环境污染现状，提出要发展城市建设，就要建设生态城市、走可持续发展的道路，同时指出重点放在凋整城市布局结构、加大市区内园林绿地的建设力度，根据城市工业布局现状(即工业污染源分布现状) ，调整城市绿地布局结构，改善城市生态环境，最后达到生态城市的标准。
Now eco - city will be the only and inevitable choice for 21 ( superscript st ) century cities due to its strengths as follows : orderly developing according to the time , reasonable space arrangement , well metabolism process , sound industrial structure , right economy , abundant landscape diversity , competition , symbiosis and spontaneity 只有以生态学原理为基础，寻求城市发展的方向和道路，协调好以人为主的人类社会经济系统与其所依赖的自然生态系统相互关系，才能实现城市可持续的富裕、健康、文明发展。
Upon the dawn of the 21st century , the social and economic system with companies as its core is facing dramatic changes , the main feature of which is the emerging of organizations characterized by it , knowledge accumulation and sharing , as well as the shift of sparseness among various resources 在人类迈入21世纪时，以企业为核心的社会经济系统正面临着一个巨大的飞跃。其基本标志就是信息技术、知识积累和知识共享为特征的组织的兴起，各种资源的稀缺性发生了相对转移，进而对原有的企业内在和外在的框架提出了挑战。
