摘要: 德庆县属南方丘陵山区,耕地详查面积较统计面积大40%,大部分耕地因洪、涝、旱、土质瘠薄而低产,高产优质田仅占30%,中低产达70%,远较传统认识的多,这在南方丘陵山区有普遍性。因此,必须进行优势开发,严格保护高产优质田,集中改造中低产田,继续大幅度调整农业结构,控制水土流失。

Abstract: Deqing is located in the tropic and subtropic mountain Area of China. Its area of Cultivated land from land use survey is 40% larger than the statistic. Of all cultivated land, owing to the flood, waterlogging, drought and barren soil, the high yield land occupys only 30%, and the mid low yield land 70%, which is far more than the percent statistic. These situations generally existed in tropic and subtropic mountain areas 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 agricaltural structure further, and to control soil erosion, are necessary to make best use of its advantages and bypass the disadvantages.
