Analysis Of Change Of Forest Land In Chifeng

Green is the necessary condition for the sustainable development of our country.The "13th Five-Year" forestry development plan proposed that the forestry authorities at all levels should constantly improve the monitoring and evaluation system,strengthen the analysis of the implementation of the plan,and establish the implementation and evaluation mechanism of the plan.Comrade Xi Jinping emphasized in the arbor day that we should treat the ecological environment just like life.On the basis of collecting two kinds of survey data of forest resources in 2001,this paper compares the two types of forest resources survey in 2016,and analyzes the characteristics of the spatio-temporal change of the woodland of the Kala Qin banner by using the dynamic degree and the change range of the land use.Through this investigation,the conclusions are as follows:(1)the survey results of two categories of resources in 2016 showed that the total land area of the administrative area of kalqin banner is 304785hm2.Among them,woodland area is 205379.6hm2,which accounts for 67.39% of the total land area,and the non forestland area is 99405.4hm2,accounting for 32.61% of the total land area.The forest coverage rate was 57.79%.The forest coverage of the villages and towns in the whole flag is very different.The vegetation in the southwest and western regions is mostly arbor,and the vegetation in the north and central areas is mostly shrubs,and most of the shelterbelt in the East is poplar farmland.(2)through the comparison and calculation of two types of data of forest resources in 2001 and 2016,the total forest area of two years increased from 169489.6hm2 to 205379.6hm2,and the net increase was 35890 hm2.The change of the woodland in the last 15 years of the Kala Qin flag is obvious.By using the method of land use dynamic degree and change amplitude,the change range of forest land category in the whole flag is no forest forest > sparse woodland > shrub > suitable forestland > nursery land > unforestland > forestry auxiliary production land > arbor woodland.
