Land Use/Land Cover Change (LUCC or LU/LC) is a hot topic of the current Environmental Ecology research. This paper analyzes Land Use/Land Cover Changes of Hailar River in 1990,2000 and 2009, and analyzes its impact factors. The following results have been achieved:1. During 1990 and 2009, the seven major land-use types in Hailar River Basin have taken place in different degrees. The cultivated land, industrial land and residential land areas which are mainly affected by human actions are increasing year by year. While the water and water facilities land areas use are decreasing. Especially the cultivated land area, its changing number and rate is in the first place of all land-use types.2. During the year of 1959 and 2009, the annual average temperature of Hailar River Basin is increasing year by year, of which the average temperature in the western grasslands is higher than the degree of eastern forest region. Its annual average precipitation, available precipitation and evaporation show a decreasing trend year by year. The temperature and precipitation show significant seasonal characteristics.3. Land Use/Land Cover Change of Hailar River Basin are caused by both natural factors and social factors. The temperature and available precipitation influence the vegetation cover situations by water balance. The population growth, economic development, social behavior and national policy are also the main of Land Use/Land Cover Change in this basin.Finally, the land optimization scheme is proposed. It requires scientific planning, rational distribution, scientific and technological input, and reduction in artificial destruction. The results of the study can provide a scientific basis, policy adjustments and rational distribution for Hailar River Basin.
