草原旅游发展中旅游管理部门环境意识的调查研究

根据环境意识结构．设计了旅游管理部门环境意识调查问卷。其主要的指标体系包括：旅游环境知识水平、旅游环境态度、旅游环境评价和旅游环境行为四个方面。对指标体系各部分之间以及每一指标部分的每一题目之间的相对重要性进行权重的确定．而且对各部分的每道题目的各个选项予以赋分。基于权重和赋分．结合调查问卷的实际情况，设计了指标体系各部分评价模型和环境意识总体评价模型。以此来计算草原旅游发展中旅游管理部门环境意识水平的综合得分。经过分析得知，旅游管理部门环境意识模式是“环境知识制约型”模式。     

人类活动对土壤环境的影响及对策

人类不合理的开发行为给土壤环境带来了沉重的负面影响，主要表现为土壤沙化、土壤侵蚀、土壤盐渍化、土壤污染等。本文以此为出发点展开讨论，分析各种现象的成因，并提出相应对策。     

基于Landsat影像的赤峰市生态环境状况评估

根据国家生态环境状况评价技术规范,基于1990,2000,2010和2015年四期的遥感和地理信息数据对赤峰市生态环境状况进行评估.结果表明：赤峰市的生态环境变化状况可以分为3个阶段,即退化期（1990~2000年）,恢复期（2000~2010年）和平稳期（2010~2015年）.4a生态环境状况指数（EI）分别为70.58、61.21、67.63和68.35,生态环境状况整体为良.赤峰市1990~2015年生态环境状况变化度（△EI）为-2.23,略微变差.从退化时期到恢复时期,△EI由负变正,表明赤峰市生态环境状况在2000~2010年期间有所改善;从恢复时期到平稳时期,｜△EI｜变小,表明2010~2015年间生态环境状况变好趋势减缓.城市化进程和水资源短缺是赤峰市生态环境状况转好趋势减缓的主要原因,因此需要进一步开展生态保护工程,并合理利用地下水资源.     

川西北草原土壤硼、锰丰缺状况初探

根据110余个表层土壤样品硼、锰含量的测定结果和土壤缺乏硼、锰的临界值指标,探究了川西北草原土壤中硼、锰的有效性及其丰缺状况.结果表明,本区土壤中全硼全锰含量丰富分别达166.0ppm和736.6ppm,但有效硼和锰的含量仅分别为0.45ppm和5.11ppm,土壤缺乏硼和锰比较普遍.为该区推广施用硼、锰微肥提供了初步的科学依据.

Biogenic VOCs emission inventory development of temperate grassland vegetation in Xilin River basin, Inner Mongolia, China

Given the key role of biogenic volatile organic compounds(VOCs) to tropospheric chemistry and regional air quality, it is important to generate accurateVOCs emission inventories. However, only a less fraction of plant species, in temperate grassland of Inner Mongolia, has been characterized by quantitative measurements. A taxonomic methodology, which assigns VOCs measurements to unmeasured species, is an applicable and inexpensive alternation for extensive VOCs emission survey, although data are needed for additional plant families and genera to further validate the taxonomic approach in grassland vegetation. In this experiment, VOCs emission rates of 178 plant species were measured with a portable photoionization detector( PID). The results showed the most of genera and some families have consistent feature of their VOCs emission, especially for isoprene, and provide the basic premise of taxonomic methodology to develop VOCs emission inventories for temperate grassland. Then, the taxonomic methodology was introduced into assigning emission rate to other 96 species, which no measured emission rates available here. A systematical emission inventory of temperate grassland vegetation in Inner Mongolia was provided and further evidence that taxonomy relationship can serve as a useful guide for generalizing the emissions behavior of many, but not all, plant families and genera to grassland vegetation.     

浅谈吉林省西部草原"三化"治理对策

随着吉林省农牧业进入新的发展阶段,结构调整、提高效益、改善生态环境已经成为现阶段农牧业和农村经济发展的重要任务,草原作为西部生态系统的重要组成部分,也是治理的重点.在结合现有的资料对吉林省西部草原"三化"的原因进行分析,并提出相应治理对策.     

建议设立『国家生态特区』

中国幅员辽阔，自然地理条件与经济发展水平千差万别。但遗憾的是，很多地区的经济及环境建设模式却区别不大。例如生态建设方面，过去几十年我们走了一条“部门工程模式”之路，即不管地区自然条件差异，而实行统一的标准和技术。如颊受争议的“三北防护林工程”，在荒漠和草原地区大量种植树木，结果树木大批死亡，浪费了国家宝贵的生态建设经费。这些工程措施中相当一部分脱离了当地的自然环境和社会经济条件，不少难免流于形式，其结果是尽管投资巨大，却形成了“点上治理、面上破坏、整体恶化”的局面。     

Relation between some variations of soil and surface vegetatio and desertization in agriculture-pasture interlacing zone an example from Kangbao County,North Hebei,China

The studied agriculture-pasture interlacing zone has its specific natural conditions,at which the natural systems are unstable ,their self-regulation capability is low and the equilibrium is easily broken, and hence the habitat is fairly vulnerable.During last 20 years the increasing population and livestock ,over-reclamation,over-pasturing,over-deforesting, and other intensified negative human activities in the zone resulted in coarsening of surface soil,decrease of organic mater content in soil, reduction of vegetation coverage ,variation and degradation of flora structure, and hence in desertization of the land, although average of gales and sandstorms some decreased and the climate tended to be better in the region.However, the frequent sandstorms occurring in the springs of last and present years has attracted much attention.Investigations confirmed that the main cause for the phenomena is the unreasonable human activites rater than the natural factors.     

基于3S技术的沙质荒漠化动态监测

该文以晋陕蒙接壤地区北部为试验区，采用70年代MSS图象、80年代和90年代TM图象，结合GPS的野外空间定位技术，在ARC/INFO系统支持下，开展了沙质荒漠化动态监测。结果表明，70年代中期至80年代中期沙质荒漠化呈发展状态，80年代中期至90年代末期呈明显的逆转状态，但二十余年来，该区的现代沙质荒漠化过程是一个复杂的物理过程，变化具有明显的不均衡性，同时建立了一套较为系统的3S技术沙质荒漠化动态监测方法。
