northwest of the LiaoNing province and the borderline of the sourtheast of the inner Mongolia province; The mostly dry land decreasing regions are the three provinces in northeast and BeiJing city, it involves northeast and southwest of the HeiLongJiang province, west of the JiLin province, west of the LiaoNing and the BeiJing city
Secondly, based on the elevation classification, slope classification、rai nfall classification、dryness classification、yearly average temperature classification, gradually analyze the Chinese farm land dynamic change in the differ background. The last decade increased Chinese paddy land area mostly under the 200m elevation, the decreasing Chinese paddy land area mostly under the IOOm elevation, it's proportion is achieve to 50%, and with the elevation higher the decreased paddy land area is litter; The rang of the increased dry land is abroad, under the 1500m elevation is the mostly. The decreased dry land is mostly under the 100m elevation. The last decade Chinese farm land dynamic change is mostly in 0}3 degree of the slope degree,and 400}800mm rainfall regions, 0.5一1 and 1一1.5 dryness range, 0}5 and 5一10 average temperature areas.
Finally, based on the Chinese landscape index approach, I analyze the last decade Chinese farm land dynamic change. Selecting the landscape variety index landscape advantage degree index, landscape uniformity index, landscape crash index,apply to analyze about the farm land dynamic change-analyze about index of the farm change type .Through the result of the experiments, the characteristic distribute of the four type index is approximately homology, the differ is consist in the distribute amount; The landscape variety index of the farm change is lower, it's distribute accords to the normal; The landscape advantage degree index is higher, it's
distribute is centralized. The landscape uniformity index is the highest, it's distribute is increase by degrees; The landscape crash index is the lowest, it's distribute iscentralized.
