During the winters of 1994 to 1996, observations and statistics were made on the dynamic status of migration, habitat form, activity babit and population density of Common crane Grus qrus Lilfordi sharpe in Yellow river beach of Hejin, Shanxi Province. The results showed that, Common crane migrate into this area in middle of October and leave until middle of March of next year. In winter, they are used to activity together, normally about 10~20 individuals. Now, totally only about 700~900 individuals are...

During the winters of 1994 to 1996, observations and statistics were made on the dynamic status of migration, habitat form, activity babit and population density of Common crane Grus qrus Lilfordi sharpe in Yellow river beach of Hejin, Shanxi Province. The results showed that, Common crane migrate into this area in middle of October and leave until middle of March of next year. In winter, they are used to activity together, normally about 10~20 individuals. Now, totally only about 700~900 individuals are reserved in this area, which is rather less than 1983, So, propose that the wintering habitats of Common crane should be strenuously protected.

1994年~1996年冬季对河津市黄河滩灰鹤迁徙动态、栖息地类型、活动习性和种群数量进行了观察、统计。结果表明:灰鹤每年10月中旬迁来,次年3月中旬迁离;冬季成群活动多在10只~20只一群;数量700只~900只左右,与1983年相比较明显下降;建议加强对其栖息地的保护。

During the last 2000 years, the climate of the northern piedmont of Tianshan mountain has varied between cold and warm, arid and humidity, but the whole arid condition has not changed. It has varied with the change of climate, as for plants, the limit of forests, the growth degree of plain valley forest and the area of the lower plain meadow. The mountain ecosystem is more stable contrary to the plain ecosystem. Rivers and lakes of the plains is not very stable and easily changed as a result of the change of...

During the last 2000 years, the climate of the northern piedmont of Tianshan mountain has varied between cold and warm, arid and humidity, but the whole arid condition has not changed. It has varied with the change of climate, as for plants, the limit of forests, the growth degree of plain valley forest and the area of the lower plain meadow. The mountain ecosystem is more stable contrary to the plain ecosystem. Rivers and lakes of the plains is not very stable and easily changed as a result of the change of the regional climate and the biology of the community. The water system in the plain has largely changed because of the variation of the climate and the human activity. It is a common phenomenon that the water quality is reducing, the flow is shortening and the ending lakes are disappearing. Because the artificial oasis took the place of the natural oasis, the function of natural oasis is weakening and nearly lost the ability of improving the environment, the habitat of wildlife and preserving the biological diversity in wild area. Since the Neolithic Age, the human being has emerged and evolved in this area, living mainly on hunting and herding, followed by herding and farming, and finally farming and herding. Therefore the human influence on the environment last a considerable long period of time. Since Qing dynasty, especially after the foundation of new China (1949), the effect has increased sharply and been the dominant factor of the variation of environment in the latter_day, which presented on controlling of water resource, and so caused the change of water system, vegetation and desert etc.

近 2 0 0 0年以来 ,天山北麓的气候有冷暖干湿波动 ,但总体干旱的基本面貌未发生根本变化。植被在森林的上下界限、平原河谷林的发育程度、平原低地草甸的面积上 ,随气候的变化而发生波动。山地生态系统比较稳定 ,平原生态系统相对不稳定。尤其是平原河流和湖泊抗干扰性极差 ,容易发生改变 ,同时也引起局地小气候及生物群的变化。由于气候变化和人类活动的影响 ,平原地区的水系变化很大 ,河流流量减少、流程缩短、尾闾湖消失、地下水位降低、扇缘溢出带北移等成为普遍现象。天山北麓是自然绿洲发育比较好的地带 ,由于人类活动的影响 ,自然绿洲大多为人工绿洲取代 ,自然绿洲功能弱化 ,基本失去了改善荒漠环境、生物栖息地、保护荒漠区生物多样性等多种生态功能。该区新石器时代以来就有人为活动 ,早期以狩猎、牧业活动为主 ;中期以牧业为主 ,农业为辅 ;后期以农业为主 ,牧业为辅 ,人类对环境的影响有相当长的时间。清朝以来 ,尤其是解放后 ,人类对环境的影响作用急剧加强 ,成为近代环境变化的主导因素 ,主要表现在对水的控制而产生的一系列水系、植被、沙漠变化

We investigated the characteristics of breeding microhabitat of Saunders' Gull (Larus saunder-si) in the spring and summer of 1999, 2000 and 2001. Three types of breeding habitats of Saunders' Gullwere recorded: Spartina anglica community, Suaeda glauca community and Aeluropus littoralis communi-ty. We compared the nesting habitat availability with nesting habitat utilization in these three habitats.The results showed that Suaeda glauca habitat was positively selected by Saunders' Cull, and Spartinaanglica habitat...

We investigated the characteristics of breeding microhabitat of Saunders' Gull (Larus saunder-si) in the spring and summer of 1999, 2000 and 2001. Three types of breeding habitats of Saunders' Gullwere recorded: Spartina anglica community, Suaeda glauca community and Aeluropus littoralis communi-ty. We compared the nesting habitat availability with nesting habitat utilization in these three habitats.The results showed that Suaeda glauca habitat was positively selected by Saunders' Cull, and Spartinaanglica habitat and Aeluropus littoralis habitat were avoided. Indicated by the studies on microhabitat se-lection, the characteristics of breeding microhabitats where Saunders' Gull prefer to nest included thatplant height is more than 5 cm and less than 25 cm, vegetation coverage is 20% to 60%, biomass of zoo-benthos is above 300g/m2, distance to water source is 500m to 1000m, and distance to artificial disturb-ance is more than 500m. Beach exploitation and human activities along the coast of Yancheng were themajor factors influencing breeding microhabitat selection of Saunders' Gull. Some suggestions are put for-ward for protection and management of breeding habitat for Saunders' Gull.

1999-2001年春夏对江苏盐城国家级自然保护区黑嘴鸥的繁殖微生境进行了调查。黑嘴鸥的繁殖生境包括碱蓬群落(Suaeda glauca)、獐毛群落(Aeluropus littoralis)和大米草群落(Spartina anglica)。通过生境可获得性与可利用性分析,得知黑嘴鸥营巢对碱蓬生境具有正选择性,对獐毛和大米草生境具有负选择性。对繁殖微生境选择研究的结果表明,黑嘴鸥繁殖微生境具有以下特征:植被高度5-25 cm,植被盖度20%-60%,底栖生物量大于300 g/m2 ,距水源距离 500-1000 m,距人类活动干扰距离大于 500 m。滩涂开发和人为活动是影响盐城地区黑嘴鸥繁殖微生境选择的重要因素。本文对黑嘴鸥繁殖栖息地的保护和管理提出了一些建议。
