为掌握石羊河国家湿地公园内植物本底资源状况,更好地保护区内湿地资源,促进湿地公园健康发展,采取野外调查和室内查阅相关文献鉴定的方法对石羊河国家湿地公园内植物资源进行了调查分析.结果为:(1)调查区内有植物197种,隶属38科123属,其中有国家稀珍濒危植物3种,特有属种1种.双子叶植物是该区内植物群系的主要建群种,分别占总科属种数的68.42％、73.98％、75.13％,丰富度高.(2)区系分析表明,该区系有10个分布类型,其中北温带分布,世界分布,地中海区、西亚至中亚分布,旧世界温带分布,泛热带分布等5个分布区类型所含属数均≥10属,温带分布型占总属数的67.8％,表明该区系植物是典型温带性质.(3)该湿地公园内植被可分为4个植被型组、7个植被型、26个主要群系,为典型的河岸地带湿地植被,具有明显的地带性特征,水分梯度影响明显.

在甘肃民勤石羊河国家湿地公园鸟类监测及植物资源调查过程中,在红崖山水库监测到斑头秋沙鸭(Mergellus albellus Linnaeus,1758),经查阅相关文献和专著,确认其为民勤县鸟类新记录;在石羊河西侧河滩地上采集到水茫草(Limosella aquatica L.),从所采集的实物标本和实拍图片中鉴定出玄参科Scrophulariaceae水茫草属Limosella Linn.水茫草Limosella aquatica L.在甘肃分布的1个新记录属种.以上2种动植物新种的记录,说明该湿地公园的生态环境正逐步改善,对研究鸟类迁徙和植物分布特征具有重要意义.

对石羊河下游柠条河岸林病虫害进行了调查,得出柠条主要病害有4种,害虫有3种,分析了其危害特点,有针对性地提出了防治对策.

The article surveyed thePopulus euphratica diseases in Shiyanghe National Wetland Park of Minqin in combination with line survey and the standard line survey. The result showed that P.euphratica branches have 2 kinds of diseases which are canker andValsa sordida Nits; leaf have 2 kinds of diseases which are leaf blight and leaf rust. The paper put forward the countermeasures based on damage characteristics.

The article records the first detection of Cygnus cygnus in Shiyang River National Wetland Park,which have two with the international combination(1T37、1T46).The findings suggested that wintering range of Cygnus cygnus was extended from Gannan plateau to the east side of the Hexi corridor,and Shiyang River National Wetland Park is an important migration path and wintering habitat for Cygnus cygnus.

在民勤石羊河国家湿地公园首次观测到国家Ⅰ级保护鸟类1种,国家Ⅱ级保护鸟类3种,分别是黑鹳(Ci鄄conia nigra)、白琵鹭(Platalea leucorodia)、灰鹤(Grus grus)、蓑羽鹤(Anthropoides virgo). 该4种鸟的发现,说明该湿地公园的湿地生态系统得到逐步改善,已成为内陆河鸟类重要的迁徙地和越冬栖息地.

在民勤石羊河国家湿地公园干旱荒漠区开展了荒漠河岸林柠条植苗造林,总结出了该湿地公园荒漠河岸林柠条植苗造林技术.

报道了石羊河下游荒漠区3个鸟类新记录,猎隼Falco cherrug、红隼Falco tinnunculus和崖沙燕Riparia riparia。该3种鸟的发现,为进一步研究该区域鸟类奠定了基础。

甘肃民勤连古城国家级自然保护区位于民勤县境内的荒漠区域内,从北、西、南三面屏障着民勤绿洲,生态区位极为重要.保护区的建设与发展,以及与周边社区的关系,不仅关系民勤绿洲的生死存亡,而且关乎到临近的武威、金昌乃至整个河西走廊的生态安全,两者之间是一种相辅相成的关系,保护区要发展离不开周边社区群众的参与,周边社区群众要发展经济同样离不开保护区发展的带动.从保护区与周边社区的关系入手,分析了保护区与周边地区协调发展面临的问题,并提出了协调发展的对策.

叙述了老虎口生态环境的演变及现状,从自然因素和人为因素两个方面分析了生态环境恶化的原因,结合民勤县林业工作实际,就老虎口生态环境治理如何结合科学发展观、破解问题,提出了治理方法。

通过麦草网格沙障与植物活沙障的观测对比,为实际造林治沙工作提供了科学数据,更好地治理了流动沙丘。

[objective]The aim was to evaluate the fixation efficiency of sand barrier of different materials, different modes , and offer some suggestions about the government of Qingtuhu. [method] By setting up sand barrier of different materials, different modes in the sand outlet, the fixing effect of the sand barrier of different types in different wind conditions were monitored and analyzed ,such as the length of preservation. [result] Straw checkerboard barriers were the most valuable ,because of the good ability to gather sand, low cost ,long life. Its cost was similar to the cost of clay sand barrier, cotton stalk , strings the grass low vertical sand barrier, non-woven bag sand barrier, polymer fixing agent sand barriers, asphalt sand barrier, ecological mat sand barrier. Nylon mesh sand barrier had the ability to gather sand and had high practical value, but expensive. So the application was limited. [conclusion] The position of Qingtuhu was complex, sand dunes appeared in crescent-shaped dunes at the altitude between 3-15 m. To achieve the maximum function of sand barrier, different parts of the dune sand barriers should be set in different positions. Meanwhile, according to advantages and disadvantages of the sand barrier, positions to fully mobilize the potential of land was made arrangement .
