| 摘 要： | 利用土地调查和统计资料分析了天津市自1949年以来耕地数量动态变化过程、驱动因子及其影响机制,并在此基础上,提出了抑制耕地流失和促进耕地增加的相关对策.1949年以来,天津市耕地数量动态变化经历了波动变化和持续缓慢减少两大阶段,耕地数量总体上缓慢减少.经济发展、人口增长、相关政策、环境变化和自然灾害等因素,对耕地数量变动的驱动作用非常明显.

| Abstract: | The dynamic change and driving forces of the cultivated land area in Tianjin was analyzed according to the statistical and survey data from 1949 to 2003.On the basis of it,some measurements for controlling decrease of cultivated land area and promoting its increase were put forward.The results indicated that the cultivated land area all decreased slowly in the last 54 years.It fluctuated before 1969,and decreased continually since the 1970s.Some effective factors such as rapid economic development,population growth,policy,environment change and natural disasters were the dominant driving force to dynamic changes of the cultivated land area in Tianjin. |
