摘　　要：Deqing County of Guangdong Province is located in the tropic and subtropic mountain areas of China. Its area of cultivated land from landuse survey is 40% larger than the statistical data. Of all cultivated land, owing to flood, waterlogging, drought and barren soil, the high yield land occupies only 30% and the mid low yield land 70%, which is far more than the percent by statistics. Because the statistic area of cultivated land is less than the actual, the per unit area yield by statistics is higher than the actual. These situations generally exist in the tropic and subtropic mountain area of South China. So the measures to protect the high yield cultivated land strictly, to improve parts of the mid low yield selectively, to adjust agricultural structure further, and to control soil erosion, are necessary to make best use of its advantages and bypass the disadvantages.
