中文摘要 | 中國大陸的農業基本上是持續發展的。當今人類面臨人口、環境、資源和食物的多重壓力,其中土地資源的質量直接關係到農業可持續發展和人類的生存。中國大陸人多耕地少,自然資源相對緊缺,如1995年中國耕地總面積為9497.09萬 ha.,人均耕地僅0.08ha.,還不及世界人均耕地的1/4。當前,中國大陸農村每戶平均使用耕地僅為0.66ha.,每個勞動力僅使用0.26ha.耕地。水資源也相對緊缺。嚴防土壤退化,培肥地力是當務之急。文中指出走現代集約持續農業發展之路,必須用地與養地相結合,因地制宜採取培肥地力的相關對策。 |
英文摘要 | Agriculture in the mainland of China has been developing in a sustainable manner. At present time, the world is under high pressure in terms of population, environment quality, resource availability and food security. The quality of agricultural land directly affects the sustainable development of agriculture and the living standard of human beings. The mainland of Chian is characterized by high population and shortage of natural resources, especially the arable land. In 1995, the total arable land in the mainland is 94.9709 million ha. The average arable land per capita is only 0.08 ha, less than 1/4 of the world average. Currently, the average arable land area per household is 0.66 ha. with one labor operating 0.26 ha only. The water resource is also limited. Therefore, there is an urgent need for soil degradation control and soil fertility improvement. To incrrease soil fertility according to local condition and to improve land productivity with rational utilization are the key components for the sustainable development of modern intensive agriculture in the mainland of China. |
