| 摘要: |
| 以县级行政区为基本空间单元，运用因子分析法，对江苏省1999年和2009年反映耕地集约利用 状况指标进行定量综合评估。结果表明:环太湖和近海的沿江地区耕地利用集约度相对有所减弱;集约化 特征南北分化明显，以太湖农区为代表的苏南地区，复种指数低、农用化学品投入少而经济产出率高，而 淮北农区则复种指数高、农业化学化程度高、劳动密集。洪泽湖以东淮河流域的农田水利化建设以及淮北 地区较高的农用化学品投入强度等问题值得重视。 |

| Abstract: |
| Using the method of factor analysis， the paper quantitatively evaluated the arable intensification of Jian- gsu province in 1999 and 2000 based on spatial unit of county. The results showed that the intensity characters of cultivation showed a marked regional difference， and declined obviously in the surroundings of Tai lake and coastal areas along the Yangtze River from 1999 to 2009. The southern Jiangsu area， such as Tai lake areas， had a low multi-cropping index（MCI） and low input of agrochemicals but high productivity， while the north Jiangsu region showed a high MCI due to high labor and agrochemicals input. It concluded that it should pay attention to the irri- gation and drainage engineering and the high input of agrochemicals in Huai river basin. |
