Research On Spatial Distribution Characteristics Of Wild Camel Based On GIS And Remote Sensing Technology

The history of the wild camel has been cultivated or semi-wildly cultivated for 30 years.The Gobi Nature Reserve A District Management District aims to achieve a steady increase in the number of wild camels,during the period from1987 to 1989-1991,artificial breeding activities for wild cubs have been carried out in the Gobi-Altai regilon.Until 1993,13 wild camels were bred in total,including 6 male wild camels and 7 female wild camels.Today,this number has reached 33.The distribution of wild camels continues to shrink,resulting in a drastic reduction in the number of individuals and may be exposed to extinction.This study uses remote sensing technology to analyze the weather forecast,vegetation index,altitude and water level in the study area.The result is the average annual surface temperature of the study area is-4.3-5.5~0C,28-31~0C in summer,and-13.8 to+6.8~0C in winter.In the warm season,the average is 20-22.The wild camel expresses the surface temperature of the wild camel below the surface temperature of the surrounding environment.The distance to the water point is the most important variable in this season.It has been observed that the location of the site is affected by the water point.Plant and soil form are the second most important variable in the whole season,and it is equally important in autumn.Because of these weather and climate conditions,the wild camel is at risk of food shortage.Vegetation coverage is less because the precipitation is not sufficient,and the rich vegetation near the oasis is directly related to moisture and humidity.Observing the model results,the wild camel prefers the average NDVI to be 0.07-0.1.Although the NDVI value is relatively small and the vegetation coverage is limited,the wild camel in this area may reasonably control the limited vegetation resources in the intake.The results of this model show that only vegetation and annual plants grown after enough summer rainfall are favored.The distribution of the wild camel varies according to the season.In addition,the age and male ratio of the camel group accounted for the main influencing factors.The situation of pastures,water resources and co-supply were also factors influencing the past year.The average distribution area of the basic camel population of captive breeding wild camel is 1635.7km~2.The distribution area of wild camel is mainly affected by seasonal changes and young camel.It has the largest distribution area in summer and the smallest in spring.The main factor affecting the spatial distribution of wild camel is water body.
