Other Abstract

Drought,serious soil erosion and fragile ecological environment are the key issues in the Northwest
China.The project of returning farmland to forestland and grassland is the important measure for the
construction of ecological environment in the northwest region,and also a magnificent ecological project of
the national ecological environment construction.Based on the integrated analysis of the present situation,
the ecological effect and the existing problems in the implementation of the project of returning farmland to
forestland and grassland,the scale of the project of returning farmland to forestland and grassland in the
Northwest China was discussed.The results were as follows.(1)The area of returning farmland to forestland
and grassland was 7.519 9million hm2 during the period from 1999to 2011in the Northwest China,
accounted for 36.14%of the returned national area during the same period.The areas of returning farmland
to forestland and grassland of the Shaanxi,Gansu,Qinghai,Ningxia,Xinjiang,Shanxi and Inner Mongolia
Midwest,accounted for 27.89%,21.29%,4.62%,9.80%,10.80%,13.57% and 12.03% of total
returned area in the northwest region in the same period,respectively.(2)Since the implementation of theproject,the net incomes of farmers in the northwest area increased year by year from 2002to 2012,and the
increasing trend of the provinces or regions was the same.(3)In northwest region,the vegetation cover was
improving,and NDVI was in the upward trend on the whole,but there are obvious differences in the space,
spatial distribution was gradually decreasing from southeast to northwest,and the northern Shaanxi is a
region with the fastest speed of vegetation recovery during recent 10years in the Loess Plateau.(4)During
2003—2014,the runoff and erosion in the Yellow River basin were lower than those during 1950—1995,and
the annual fluctuations were large.(5)the area of slope farmland with more than 25degrees was 1.801
million hm2,accounting for 6.0%of the existing cultivated land,area of slope farmland with 15~25degrees
was up to 2.965×106 hm2,accounting for 9.9% of the existing land area,and the farmland scales of the
provinces or districts were clarified,and finally,four suggestions were put forward to aim at the smooth
implementation of farmland policy of a new period.
