有关鸟类与环境的调研摘要:鸟类与环境息息相关,环境可以通过温度、降水量、繁殖地等因素来影响鸟类。
同时,一个地区的鸟类种类和数量的变化也可以说明这个区域环境的变化。
Abstract: the birds and the environment, the environment through temperature, precipitation, and other factors to influence the breeding ground for birds. At the same time, changes in the number and species of birds in an area can show the change of the regional environment.关键词:鸟类;环境;环境容纳量;区域环境Keywords: birds; environment; environmental capacity; regional environment鸟类是大自然中最常见的一类动物,而且处于食物链的中上层。
为此鸟类与我们身边的周围环境可以说是息息相关。
首先,鸟类的生存和繁殖,就必须从周围环境中获得食物和生存所必须的一切条件,环境会对鸟类产生一定的影响。
当鸟类减少时,那么一定说明环境水平下降。
同时,鸟类的兴衰存亡也会对周围的环境产生一定影响,它们有着十分密切的关系。
在全世界中,鸟类共有9 000多种,估计有1 000亿只。
它们的食性复杂,生活方式多样,栖息在各种生态环境中,是维护自然界生态平衡的重要因素。
The bird is a kind of animal is most common in nature, and in the pelagic food c hain. This bird and our side of the surrounding environment can be said to be closely linked. First of all, survival and reproduction of birds, we must get all the conditions needed for food and living from the surrounding environment, the environment will have a certain impact on birds. When birds are reduced, so that environmental degradation. At the same time, the birds rise and decline will have a certain impact on the surrounding environment, they have a very close relationship. In the whole world, there are 9000 kinds of birds, is estimated to have 100000000000 only. Their diet complex, life style diversity, habitat in the various ecological environment, is an important factor to maintain the natural ecological balance.1环境对鸟类产生的影响。
Effect of environment on the 1 birds.对于鸟类来说,一种鸟要灭绝,其主要因素并不是人为大肆捕捉,而是因为环境恶劣,该种鸟的环境容纳量下降。
而人对鸟类的影响也通常是通过环境的破坏来影响鸟类。
For a bird, a bird to extinction, the main factor is not human 's capture, but because the environment is bad, the bird environment capacity decline. And the influence of the birds is usually also to affect bird by the destruction of the environment.1.1温度当一个地方的环境气温上升或者下降超过一个鸟类可适应的范围,那么鸟类的正常生理活动就会受到干扰。
此时,鸟类就将发生迁徙,离开这个地方。
最明显的例子莫过于冬候鸟、夏候鸟的迁徙。
同理也是如此,当这个地方的温度上升时,会出现原先许多不常见的鸟种。
随着全球气温回暖,在1980年后,福建省的日常温度相较于之前高0.6℃。
所以从1980年起,在福清发现第一只黑翅鸢后,接下来的数十年间,福建省各地陆续发现黑翅鸢的踪迹。
黑翅鸢目前已经成为福建省的留鸟。
而之前该鸟种一直存在于海南等地。
1.1 temperature when a local temperature rise or fall more than a bird can be adapted to a range, then the birds in normal physiological activity will be disturbed. At this time, the birds will have to migrate, leaving this place. The most obvious example of migration than winter, summer migratory birds. Similarly also is so, when the local temperature rises, there will be many of the original is not common bird species. With the development of global warmer temperatures, in 1980, before the daily temperature of Fujian province compared with the high temperature of 0.6 ℃. So from 1980, found the first Black-shouldered kite in Fuqing, for decades to come,/ /Fujian province have found Black-shouldered kite. Black-shouldered kite has become the Fujian province resident. And before the bird species have been found in Hainan.1.2降水量一个地方降水量过高或者过低时,都会通过影响鸟类的繁殖行为和生存难易度来改变鸟类的数量。
白鹤是一种极度濒危的迁徙性湿地鸟类,全球野外大约有3 000只个体。
白鹤过去经常在中国的长江中下游越冬。
但随着97、98年降水量减少,强降水天气增多,对白鹤的栖息地产生负面影响。
致使那两年间,在长江流域的白鹤数量由原先的1 200只锐减至200只不到。
1.2 of the precipitation of a local precipitation is too high or too low, will be affected by avian reproductive behavior and survival difficulty to change the number of birds. The crane is a critically endangered migratory birds in wetland, the global field of about 3000 individuals. The crane used in the lower reaches of the Y angtze River in china. But with 97, 98 years of reduced precipitation, increased precipitation weather, the negative impact of crane habitat estate. In those two years, the number of white crane in the Y angtze River Basin from 1200 dropped to 200 less than.1.3生存环境随着工业化城市化进程的加快,人们围湖造田、开山采石,利用滩涂地养殖,破坏红树林等行为已经成为影响鸟类生存的最大环境因素。
黑脸琵鹭是近几年最受鸟类工作者关注的一种鸟。
在70年代之前,黑脸琵鹭常见我国华南地区,随着近期的调查,发现目前该鸟在世界仅存不足1 000只。
在黑脸琵鹭的最大越冬地台湾,其西北沿海正受到工业化的严重威胁,香港米埔也受到污染,越南尽管在它的越冬地建立保护区,但仍受到连续地将泥滩改为水产养殖场的威胁。
这些人为因素使其食物来源减少,水源受破坏,繁殖地受人为干扰。
在福建省的泉州湾湿地保护区,这2年随着环境的开发,泉州换成公路的修建,破坏了部分山体和滩涂地,原先每年在此进行繁殖的白鹭、牛背鹭、苍鹭、大白鹭的数量也由原先的近万只顿减为目前的千把只。
这也是由于修路过程中,破坏鹭类的巢穴,施工过程的噪音和人为走动干扰其繁殖地造成的。
1.3 living environment with the city to accelerate the process of industrialization, people reclaiming land from the lake, quarrying, the destruction of mangrove beach culture, such behavior has become the biggest environmental factors influence the survival of birds. The Black-faced Spoonbill is in recent years most birds birds of the workers concerned. Before 70 time, Black-faced Spoonbill common area of our country Southern China, with recent survey, found the bird only less than 1000 in the world. In the largest wintering Black-faced Spoonbill in Taiwan, the northwest coast is under serious threat of industrialization, Hongkong Mai Po is contaminated, Vietnam despite the establishment of protected areas in its winter, but still is continuously the mudflats to aquaculture threat. These factors reduce their food sources, water damage, a breeding ground for jamming. In the Gulf of Quanzhou Wetland Nature Reserve in Fujian Province, the 2 years as the development environment, Quanzhou for highway construction, destruction of parts of the mountain and the beach, the original number here annually breeding egrets, cattle egrets, herons, great egrets from the original nearly million cuts for the thousands of the only. This is due to the road in the process of destruction of herons, nest, construction noise and artificial breeding to ambulate interference caused by.2决定环境的鸟类因素2 factors determine the environment of birds2.1鸟的种类不同的鸟类对同一个地方的适应能力不同。
