林业资源型城市可持续发展研究

林业资源的可再生性使林业资源型城市的区域发展问题在一定程度上不同于其他类型的资源型城市。文章对比分析了林业资源型城市与其他类型资源型城市的差异性,认为林业资源型城市的发展问题具有"过渡期"性质。从区域内生发展能力、替代产业发展的区位制约、林区功能转换以及林权等角度分析林业资源型城市的发展障碍,并探讨了资源替代、森林保育基地及林业资源综合开发三种发展模式及其存在问题,继而提出林业资源的综合开发是林业资源城市保持竞争优势,实现可持续发展的有效模式,并提出相应的对策和建议。     

地方图书馆林业文献资源建设的现状与对策

忻州市林业资源丰富,境内有五台山、禹王洞、赵杲观和管涔山四个国家级森林公园。全市林业用地面积102.91万公顷,森林覆盖率达到17.09%。近年来,忻州市在“退耕还林”、“天保工程”、“防护林工程”、“京津风沙治理工程”、“自然保护区建设及野生动植物保护工程”以及通道绿化等方面取得了显著成绩。林业事业的发展为林业图书情报工作提出了新的挑战,也为地方图书馆开发馆藏林业文献资源、开展林业科技信息服务带来了新的历史机遇。　一、地方图书馆林业文献资源建设现状林业科技情报主要来源于地区文献信息部门——林业科研单位、公共图…     

河南黄河下游林业发展潜力与对策

从河南黄河下游自然和社会经济情况入手,在深入分析林业综合开发的土地、树种、湿地资源潜力以及木材、经济林产品和森林旅游需求的基础上,提出了河南黄河下游林业发展对策;对林业综合开发的投资和效益进行了初步探讨。     

浅谈天然林保护工程的科技创新

<正> 天然林资源保护工程等林业重点工程实施以后,对林业科技的发展提出了一个重大课题,那就是如何推进林业科技进步和创新,实现林业跨越式发展。现在大家基本上形成了一种共识:要实现林业的跨越式发展,首先必须实现林业科技的跨越式发展。要实现林业科技的跨越式发展,必须依靠科技创新。 首先,天保工程实施以后,标志着我国林业开始从以木材生产     

黑龙江省“七五”、“八五”林业科技投入水平与发展态势

<正> 对黑龙江省林业科技投入水平及发展态势的评价包括了三个层面的内容,一是人才资源的投入水平与发展态势,重点分析评价林业科技人员的总量、素质、年龄和职称指标的配置水平;二是资金资源的投入水平与发展态势,主要分析评价林业科研经常费收入与支出指标的配置水平;三是资产设备资源的投入水平与发展态势,主要分析评价林     

开展名特优林果种质资源保护利用增强山东林业发展后劲

<正> 近几年,随着国民经济的发展,林业的生产和建设取得了巨大的成就,特别是“八五”期间,山东省林业科技硕果累累,生产发展迅速。如何保持林业发展的良好势头,将林业事业进一步推向前进,还面临着一系列问题。开展名特优林果种质资源保护利用,是促进科技与经济有机结合,增强林业发展后劲,实现林业两个根本性转变和可持续战略的关键。     

林业生态环境监测数据采集

近年来 ,我国将森林资源的保护、林业的可持续发展、生态环境建设提到了前所未有的高度。然而 ,由于体制和技术等多方面的原因 ,仍然面临着森林资源保护和生态环境建设的诸多亟待解决的问题 :国家的林业资源和生态环境的基本状况如何 ?各地区的资源与环境有哪些特点和问题 ?各地区应该采取哪种技术和发展模式 ?这些问题的解答 ,迫切需要掌握全面的、系统的、可靠的、翔实本底资料。但是目前尚无系统的、全面的林业资源和生态环境基础数据。。林业生态环境监测数据采集的目标是将生态环境的保护、建设及研究长期积累、采集的分散的、缺乏统一…     

以《决定》精神为指导 加速林业经济结构的战略性调整

<正> 中共中央、国务院颁布实施的《关于加快林业发展的决定》中指出,实现加快林业发展的主要目标,就必须加快林业结构调整步伐,提高林业的经济效益。因此,作为中国林业重要组成部分的国有大型森工企业,应站在“全面建设林区小康社会”的高度,认清全国林业加快发展的新形势,联系实际,找准林业发展定位,在建立较为完善的生态体系的同时,努力推进林业产业结构升级,最终实现林区经济社会的可持续发展和资源的可持续利用。     

林业法律法规与文献资源采集和共享

科技创新很大程度上取决于对知识信息与市场需求信息的获取和利用能力 ,竞争的基础是掌握知识和技术 ,科技文献作为一种可再生、可传播和可共享的国家战略资源 ,是提供知识和技术的源泉。一个国家文献信息资源的系统收集、积累、开发和利用水平 ,是国家科学技术能力、知识储备能力和信息占用能力的重要标志。林业科技文献信息是林业决策部门进行科技决策和生产部署的参谋 ,是观察、追踪国内外林业科技动态的尖兵 ,是传播信息、推广成果的桥梁 ,也是促进林业科研、教学和生产发展的重要手段。信息落后 ,就会制约林业生产的发展。实践已证明 ,…     

产学研结合是科技成果转化为生产力的切入点

<正> 新中国成立以来,我国林业事业虽然有了很大发展,但林业科技、教育相对落后,林业建设仍然处于面积大、产出少、用工多、效率低,资源浪费严重、产业极不发达、技术水平低下、经营管理粗放的落后状态。要改变这

Deserts and Aeolian Desertification in China: Book review and some thoughts

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world＇s largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing.
