贺兰山野生大型真菌孢子多样性分析

为探讨贺兰山野生大型真菌孢子的多样性,2012-2016年在内蒙古贺兰山南寺和哈拉乌沟两地进行取样,每个样地分别由5人从沟谷入口处进行拉网式调查,共获得4 000余份样品,经过微观形态观察和基因ITS序列比对,鉴定出8目25科69属189种大型真菌,主要对其孢子形态特征、表面特征及长宽比进行分析,得到如下结论:质量性状上,孢子形态特征和表面特征相互独立;数量性状上,大小孢子长宽比、孢子极端比和平均比均具有一致性和关联性,显示孢子数量特征的稳定性;菌种间孢子质量性状和数量性状具有很强的多样性;按照孢子多样性低、中、高分类,贺兰山野生大型真菌物种数分别为152种、26种和11种;孢子多样性分类为大型真菌鉴别、分类提供了基本依据。

哈纳斯自然保护区植被特点及植物区系形成的探讨

哈纳斯自然保护区的植被充分反映了欧洲－西伯利亚区系成分的特色。山地针叶林带与天山相比显著下降，为阴暗泰加林类型。植被类型丰富多样，与天山的植被特点迥然不同。本区植物区系形成于第四纪。其区系组成以温带成分为主，并含有少量的古地中海成分。以本土发生的安哥拉区系成分米体；发源于华夏地区的亚洲温带成分渗透至本区；残存的古地中海成分有小部分通过相邻地区向本区渗放。     

新疆哈纳斯自然保护区地衣群落的聚类分析

我们根据多年的实地调查结果并采用聚类分析方法对分布在哈纳斯国家级自然保护区的地衣群落进行了研究。结果表明分布在该地区的地衣种类有 10 3种 ,他们分别属于 2 0科 ,4 0属。地衣物种形成了 6种群落。同时发现该地区地衣对基物形成专一性 ,它们的基物包括 :树皮、藓丛、藓土、草地、石面、地面、土层、石浮土等。     

新世纪保护区面临的挑战及其有效对策

道路、水库、建筑物、不断扩大的农田和土地退化正在使自然景观的完整性受到严重破坏。所保存的未经干扰或少受干扰的天然生态系统的面积日益缩小，犹如海洋中的孤岛。生物多样性受到严重的威胁。在自然保护区中，物种迁移和基因流动的可能性也在不断地降低。生物区域规划被认为是一种较好的选择，它力求把保护区和栽培地区视为一个有机整体，遵循保护和发展密切结合的方针，制定行动计划并予以实施。本文根据保护区的管理情况、工作条件和科研状况等，对保护区或区域的类型进行了划分，针对现实，提出了如何实施生物区域规划。     

Are health benefits of physical activity in natural environments used in primary care by general practitioners in The Netherlands?

There is a growing body of literature showing that physical activity and nature have a positive effect on people's health and well-being. Additionally literature indicates that there may even be a synergic benefit from being physically active whilst simultaneously being directly exposed to nature. This insight is used in recovery programmes for work related stress and mental health care settings. However, as primary care is usually people's first point of contact with the health care system, the greatest benefits for people's health can probably be obtained in primary health care settings. The aim of the present study is therefore to investigate to what extent general practitioners advise patients on physical activity and whether they refer to the additional health benefits of physical activity in a natural environment.

A secondary analysis was performed on a random sample of 2784 video-taped patient consultations of 100 general practitioners in The Netherlands. Many characteristics of these consultations were known on the basis of earlier analyses: diagnosis, age and sex of patient and whether or not the issue of physical activity had been brought up by either patient or doctor. First, we investigated to what extent and with which health problems advice was given concerning physical activity. Second, from these consultations, a stratified sample of 100 consultations was observed in order to investigate whether an advice was given by the general practitioner concerning the additional benefits of nature. In 26% of all consultations advice on physical activity was given by the general practitioner. Physical activity was mentioned more often in cases of vague complaints than in cases with a clear cut diagnosis. As could have been expected, physical activity was mentioned relatively frequently in cases of musculoskeletal complaints and complaints of the nervous system. The additional benefits of physical activity in natural environments was not mentioned during any of the consultations.

In conclusion, general practitioners regularly give advice on physical activity. However, they fail to mention that physical activity in nature areas might have additional health benefits. Given the fact that medical treatment is increasingly evidence based, we think the evidence for the health benefits of physical activity in nature needs to be stronger. Results from such research could eventually find their way into the guidelines of the general practitioners.     

祁连山自然保护区康乐自然保护站野生动物调查与研究

为进一步查清祁连山自然保护区康乐自然保护站辖区内野生动物资源现状,全面、准确地掌握野生动物资源的动态变化,分析变化的原因,提出保护管理与合理利用对策,更好地贯彻执行《中华人民共和国野生动物保护法》及《中华人民共和国陆生野生动物保护实施条例》,进行了为期2a的针对康乐保护站辖区内国家Ⅰ、Ⅱ级和省级重点保护野生动物的全面调查,并针对辖区环境情况,分析研究影响动物活动的因素,提出整改措施。     

祁连山林区积雪分布规律调查

以祁连山西水林区排露沟流域为代表研究祁连山林区春天积雪分布规律,表明祁连山林区积雪分布与海拔高度关系极大,海拔越高,积雪越多;在较小尺度上,积雪分布与坡向、植被类型、林分郁闭度等因子有关,主要受森林植被影响,森林植被形成积雪小环境.     

奇台县荒漠类草地自然保护区植物区系
