| ［目的］从耕地的生产功能、生态服务功能、社会保障功能和景观文化功能角度出发，探讨耕地系统中非耕作生境对这些功能的影响的方向和程度，以期为今后耕地系统中生态网络优化以及绿色土地整治提供参考。［方法］文章运用3S技术法提取非耕作生境数据，按照非耕作生境比例由低到高在辽宁省沈阳市沈北新区水田区选择调查点。运用层次分析法计算调查点耕地多功能值，运用统计分析法研究非耕作生境比例变化对耕地生产、社会保障、生态服务及景观文化功能的影响。［结果］（1）当非耕作生境比例低于22.54%和17.16％时，随着非耕作生境比例增加耕地生产、社会保障功能呈增强趋势； 当其比例大于22.54%时和17.16％，随着非耕作生境比例增加耕地生产、社会保障功能呈减弱趋势。（2）随着非耕作生境面积比增加，耕地生态服务和景观文化功能均呈增强趋势。（3）当非耕作生境面积比低于22.54%时，随着非耕作生境比例增加耕地多功能呈增强趋势； 当其比例大于22.54%时，随着非耕作生境比例增加耕地多功能呈减弱趋势。［结论］非耕作生境比例对耕地生产、社会保障功能影响均呈现先增后减趋势，对耕地生态服务功能、耕地景观文化功能的影响趋势均呈现递增趋势，对耕地多功能综合影响呈先增后减趋势。 |

| Abstract: |
| Non-cropped habitats in farmland play a significant role in biodiversity and arable land multifunction. At present, the arable land multifunctionwasreduced with the drop of the non-cropped habitats. Therefore, theconstruction of farmland landscape ecology becomes more and more important. In this paper, the 3S technology method was used to extract data of the non-cropped habitat on arable land. Taking 15 villages in paddy field area in Shenbei new district in Shenyang city,Liaoning province as investigation objects, it used the analytic hierarchy process (AHP) to evaluate the arable land multifunction. The statistical analysis methodwas used to analyze the influence of the non-cropped habitat on arable land production function, social security function, ecological service function, landscape and culture function. The results showed that:(1)With the increase of non-cropped habitats,the arable land production function and social security function decreased. When the proportion of non- cropped habitat area was below 22.54% and 17.16%,non-cropped habitat proportion increased, and the cultivated land production function and social security function showed a trend of increase. (2)the effect of non-cropped habitatson the ecological service function and the landscape cultural functions of arable landshowedan increasing trend. So the ecological service function and landscape cultural function of cultivated land were enhanced with the increase of the proportion of non-cropped habitat.(3)The effect of non-cropped habitats on the arable land multifunctiondecreased. |
