随着城市社会经济的发展，城市林业的重要性越来越受到世界各城市的肯定并给予关注和重视。本文引述城市林业的历史以及建设城市林业的必要性，提出城市林业的概念、范畴及其地域范围，简要介绍南宁市城市自然环境条件与社会经济概况，依据2000年南宁市城市绿化普查及1999年南宁市郊区森林资源清查等资料，概述该市林业资源现状，并对南宁市城市林业的城市绿化、林种结构、生物多样性以及林业综合开发等进行分析评价，针对存在问题及城市林业未来的发展趋势提出南宁市城市林业可持续发展的对策：1加强生态文化宣传教育；2坚持城市林业的定位发展；3坚持"三同步"、"三统一"的方针原则；4转变经营部门职能，旨在为南宁市城市林业的建设和发展提供参考。关键词城市林业；城市概况；现状分析；可持续发展

The objectives of this paper were to investigate the simulation and design of continuous multiple-station rolling forming process for a U-Section Steel Bar by CAE software-DEFORMTM Due to the limitation of elements number using a short strip 120mm went through all the stations to simulate the real continuous rolling forming on factory The roller gap was fixed as 0 30mm roll speed was 20 rad/sec and progressive angles were all equal for each rolling process which were the formed angle divided by by the number of station Three rolling processes were selected with 6 9 and 12 stations respectively During simulation processes two cases occurred Case A the strip was through a single station Case B the strip across two stations Because the strip laterals side was stretched and twisted during the process The model of case B closer to the practical process than case A and the calculated stress and strain on the tip of U section for case A were lower than these for case B by up to 15% From the result of case B for each process the stress for 12-station process was smallest 9-station process second and 6-station process next Because less-station can save larger cost and forming time but the bigger stress and strain for 6-station caused wrinkles on lateral sides not found on 9-station and 12-station Therefore 9-station process was a more suitable design than 12-station process smaller stretched and twisted and stress The progressive angles for 12-station was 7 5?

本文主要是以DEFORMTM有限元素软体模拟U型钢片连续道次成型与单一道次成型以确认单一道次模拟的是否可取代连续道次模拟之研究。因DEFORMTM 软体对於网格元素上的限制故使用较短素材120mm通过所有的成型站以模拟工厂实际连续成形方法。辊轮间隙固定为0 3mm；辊轮转速为20 rad/sec；弯曲角度的方法为将成型角度平均除以成型站数。有三种辊轮成型方式被选择分别为6站，9站，与12站。在模拟的过程中有两种现象会产生 Case A，素材通过单一成型站。Case B，素材会通过两个成型站。因为在模拟过程中素材的两端会有拉应力与扭力。Case B的模拟比Case A像实际的制程，并计算应力与应变在U型断面的Tip部中可发现Case A比Case B低约15%。从Case B的每站的结果可以得知，12站的成型应力最小，9站次之，6站最后。

Finally, After overall analysis of 28 listed companies'annual report in 2007 which own forestry biological assets, there is reasonable conclusion that the fifth rule of biological assets in national Corporate Accounting Principles needs further revise and improvement, the main tasks are to revise the form of item listing in accounting statements and increase additional reporting content, namely forestry biological assets should concentrate to list the three types of consumption, production and public welfare, add detailed list related to forestry biological assets, increase the reporting requirement of forestry biological assets'categories and amounts or volume, reporting the listed companies about their methods of accounting and valuation and cost situation mandatorily, and last, report the other related information about forestry biological assets.

3对拥有林木类生物资产的28家上市公司2007年年报的分析研究，认为我国《企业会计准则第5号--生物资产》关于林木类生物资产会计信息披露规定需要进一步修订和完善，其主要内容是改进会计报表中项目列示方式和增加附表、附注披露内容，即林木类生物资产应将消耗性、生产性和公益性三类集中列示；增设相关林木类生物资产明细表；增加林木类生物资产种类和数量披露要求；强制性披露上市公司林木类生物资产核算办法、计价方法及费用归集情况；自愿披露林木类生物资产其他相关信息。
