Conclusion analysis and reporting
1 first of all,the sparrow,magpie,magpie is one of the most common birds in the campus,with its wide distribution,frequent activity,as the campus the most easilyobserved birds.Secondly,according to the landscape management workers,observation area is more suitable for the three birds perched,other species less,reflected in the survey results that the performance of bird species the basic fixed,remove the great spotted woodpecker,crow perched birds occasionally,birdspecies in this region was not increased after water injection.In addition,the three birds are resident,long-term activities in this,therefore excluding migratory bird species may lead to a substantial reduction in.From the data reflect the situation to judge,the Lotus Pond water injection or not does not directly affect the increase and decrease of bird species.Personally think that is due to the small area of waterenvironment of campus,and with the surrounding green belt is not organic to combine to create a like birds,attractive and superior living conditions like wetlandenvironment.Although the observation area can satisfy the water demand of birds,but birds drinking less in any place where water can solve this problem.So theobservation area despite the water can not attractive enough to attract birds,"come".
The breeding period of 2 sparrows,concentrated in the 3-4 month,the observationperiod is from mid April to early 5,not the breeding peak,so the investigation and Analysis on the number of birds breed increases as ignored,so the exclusionpropagation effect on the statistical results.
Secondly,because of the resident,so the number of little change,recordedstatistics basic long-term activity observed in the region of birds.At the same time,because the water area is limited,and dead,so the bird's attraction to the general,leads to the birds' quantity does not increase as a result of water injection.Once again,from the observation of several days,the bird habitat selection is not towater environment,and more inclined to their habits,such as selection of tree species distribution.Like a magpie found in 2,3 District,where the poplar,cypress and so on magpies like habitat species relative concentration.
Thirdly,from the table 2 can be found,the number of birds after water injection is generally lower than the water before.Water injection and the birds had no significant effect,but the water has attracted many people to go for a walk,exercise.At the end of April when water close to five one,so the five one holidays,the noisy.In addition to Lotus Pond after water injection started spraying waterfountain,the sound is quite large,resulting in the number of birds inhabit Lotus Pond reduced,and trees to water a little bird,back water side,gathered a lot ofbirds.In view of this,the noisy environment become an important reason for waterbirds reduced.
3 first of all,is of great significance to the whole biosphere development cycle ofwater.The campus has established the water environment helps to enrich the campus environment,provide the environment for the development of biological diversity.
Secondly,only by recording and statistics of the survey so limited,must not be arbitrary in the overthrow of the campus water environment Habitat has a direct impact on the proposition of birds.Although the campus water environment cannotprovide wetland ecological space birds as complete,but at least can meet the needof water birds,can help stabilize campus number and variety of birds.The establishment of the campus water environment can not only beautify the campus environment,add to the fun,and the growth of plant,animal,living very favorable.Ifthe campus area large enough to be planning a large lake,such as the Peking University Weiming lake,Wuhan University,East China sea.If the water area is large,the air is moist and fresh,it may attract more birds to nest or stay.
