- Abstract:
-
Talatan area is located Gonghe basin.After 1980s,ecology worsening questions such as the local lawn serious degeneration,desertification intense development are extremely prominent.The primary degeneration causes are analyzed based on the change characteristics of temperature,precipitation,gale,sand storm and lawn evaporative power in Gonghe basin in resent 50 years.Results indicated that temperature presents the obvious trend of escalation,the precipitation presents the weak increase tendency,the evaporation rate and the lawn evaporative power presents the trend of escalation during 46 years.Through two issue of TM satellite remote sensing phantom interpretation in 1987,1996 and two issue of desertification general surveys and monitor in 1994,1999,it further indicated the Gonghe basin Talatan lawn desertification is expanding.The conclusion proved that the Talatan lawn desertification expansion is a result which the climatic change and the humanity force together,the unreasonable humanity activities to the desertification occurs with expanding the acceleration,the aggravating function.
