- 摘要:
- 利用1990年和2000年夏季1：10万TM遥感影像，分析了山东省栖霞市10年间耕地资源的动态变化。结果表明：改革开放10年间，栖霞市耕地数量明显减少，耕地的主要流向是园地、住宅用地、工矿仓储用地、交通运输用地，耕地的增加主要是未利用土地的开垦和工矿用地的整理与复垦。农业内部结构调整、经济发展和政策是栖霞市耕地面积变化的主要宏观驱动因子。
- Abstract:
- Dynamic change in arable-land resources in Qixia between 1990 and 2000 were studied with the aid of remote sensing.The results showed that there is a trend of obvious decrease in arable-land area during the past 10 odd years of the reform and opening to the outside world.The decreased arable-land is mainly inverted to orchard,residential area,mine and storage land,all kinds of traffic lands.The increased arable-land mainly comes from exploitation and reclamation of non-utilized land and arrangement and resuming of mine and storage land.The structural adjustment inside agriculture,economic development and policy are the dominant macro-driving factors in decrease of cultivated land area in Qixia city.
