But at present the forests that can be cut down are fewer, so that the forestry industries are very difficult, and the situation has been very hard for the economic activities for the people there and the sustainable development of the city. Under such background, this paper does research on the problem of the sustainable development in the forestry resource-based city, find the relationship between the cut of the forest and economic development, and the problems in the economic develop process and the reasons of the declining. Then I construct the dynamic model of the sustainable development in economic in Yichun, in order to find the reciprocities among the population, resource and economics to provide more scientific data to the deciders. From the model, we can get the sustainable mode in the forestry resource-based cities.

本文就是在这种背景下，研究林业资源型城市的经济可持续发展问题，探讨林业资源开发与经济可持续发展的耦合关系，以及林业资源型城市经济发展存在的问题及经济衰退原因，并通过建立伊春市发展的系统动力学模型，进而揭示出城市发展过程中，人口、资源、经济之间的相互作用关系，为决策者做出正确的决策提供更加科学准确的技术支持，试图找出林业资源型城市可持续发展的系统优化模式，同时，把系统动力学方法引入林业资源型城市经济可持续发展研究领域，为解决相关问题探索一种新的方法与思路。

Results The age of the onset of symptoms ranged from 3 to 12 years. The clinical attacks lasted a variable time from 1 hour to more than 3 weeks. Definite medical causes were identified in 78% of the patients. Each patient had a prolonged change of consciousness, accompanied by psychological and behavioral changes. The characteristics of ictal EEG in CPSE patients generally included slow activity and δ or θ activity in the temporal region. After antiepileptic drug treatment, the conditions of 11 patients were under complete control, 4 patients had no CPSE but complex partial seizures, and 2 patients had no improvement.

结果 17例CPSE患儿起病年龄为3～12岁，临床发作持续时间为1 h～3.5周；78%的患儿有明确的病因，CPSE临床表现多样，所有病例均有意识障碍，同时伴有不同程度的精神和行为异常，发作期脑电图主要以基本电活动变慢伴颞部局灶性慢波或痫样放电的持续或周期性发放为特征，经抗癫痫药物等治疗，11例患儿持续发作完全控制，4例持续状态控制，仅有部分性发作，2例未能控制。

Based on the theories of sustainable development,index system of forest resources sustainable management and comprehensive evaluation of urban forest,the index system of measure the urban forest sustainable development have been put forward.
