摘要
通过对建国以来我国实有耕地面积增减变化的分析 ,否定了根据耕地统计面积得出的“1 95 7年以来我国耕地面积基本呈下降趋势”的说法。 1 95 3年全国查田定产得出的耕地面积 1 0 85 3× 1 0 4 hm2 最能代表建国初期我国实有耕地面积 ,此后直到 1 96 0年 ,耕地统计面积基本能反映我国当时的实有耕地面积。除“大跃进”时期外 ,1 980年前我国耕地面积基本上是不断增加的。 80年代初期全国实有耕地面积1 32 5 0× 1 0 4 hm2 ～ 1 3970× 1 0 4 hm2 ,比 1 95 7年净增 1 / 5～ 1 / 4左右。近 1 5a来我国耕地面积不断减少 ,1 996年全国实有耕地面积 1 30 0 4× 1 0 4 hm2 ,比 1 980年净减少 5 2 9 2 7× 1 0 4 hm2 ,年均净减少 35 2 8× 1 0 4 hm2 。
Based on the analysis of the actual increase and decrease of the cultivated area since the founding of the Republic of China,this paper refuted the statement that China's cultivated land has been basically desended since 1957 according to statistics of cultivated land area.However,land measurements and output setting carried out throughout the country clearly showed that the actual cultivated area being 10 853×10 4hm\+2 is most representative in the early days of New China.The statistics can simply reflect the actual cultivated area in China until 1960.Except \!the great leap forward\' period,the area under cultivation in China had continually increased in the main before 1980.It was then 13 250×10 4 to 13 970×10 4hm\+2,an increase by 1/5 to 1/4 than that in 1957.But in the last 15 years,China's cultivated land area has been decreasing gradually.
