- 摘要:
- 利用1982～2002年的统计和普查资料、土地利用调查数据及TM影像，对上黄试区20年的耕地变化及驱动因子进行了分析。结果发现耕地变化态势表现为耕地面积总量减少，耕地动态变化主要表现为坡耕地转为林地和草地，耕地质量较好的部分转为经济效益更高的园地。造成耕地变化的主要因素是人口增长、退耕还林还草和经济利益驱动等。
- Abstract:
- According to statistical and survey data, land use survey data and TM imagines from 1982 to 2002, dynamic changes of quantitative and regional difference of cultivated land and in Shanghuang experiment area during the last 18 years are analyzed. Based upon which, the major driving forces that influence the changes of cultivated land are discussed. The results indicated that the general trend of cultivated land during the past 20 years was decreasing and regional differences of cultivated land was very notable. The dynamic change of cultivated land shows sloping farmland change to forest land and grassland, some good quality of cultivated land change to high economic beneficial garden plot. The increase of population, economic benefits and land conversion from farmland to forest of grassland are the major driving forces that affect farmland change.
