| 以上高县土地整治项目为例，运用实地采样调研、室内分析化验与GIS 技术相结合的方法，根据上高县
上轮耕地质量等级更新的方法、参数体系、评价因素及权重，对上高县2011、2012 年土地整治区域耕地质量等级进
行评定，确定整治后耕地的自然等、利用等、经济等，并分析整治前后耕地质量等级变化的原因。结果表明院整治后耕
地质量等级总体提升曰整治后耕地田间基础设施明显改善，灌溉排水条件变化比较明显，土壤养分状况变化不太明
显，说明土壤养分跟土壤本底质量有很大关系，难以在短时间内发生大变化曰土地整治项目对耕地质量的影响会随
着时间的延长而持续发挥作用。 |
| 英文摘要: |
| This paper took land consolidation project in Shanggao county of the southern China hilly region as an
example, applied methods consisted of outdoor field survey, indoor test analysis and GIS technology, used the former round
of the cultivated land quality grade update method, parameter system, evaluation factors and weights to evaluate the
cultivated land quality grade in the land consolidation construction area in 2011 and 2012, and finally got the results
including the economical grade, utilization grade and natural grade of the cultivated land. At the same time, this paper
analyzed the reasons caused the change of the cultivated land quality grade, which appeared before and after land
consolidation project. The results showed that, compared with the cultivated land quality grade before the land
consolidation, the cultivated land grade rose after land consolidation. The basic infrastructure and drainage condition in the
field improved obviously but the soil nutrients had slight change, this showed that the soil nutrients and the soil quality
were interrelated after the land consolidation project, the soil nutrients could not change in a short time. The effect of land
consolidation project on soil nutrients would be obvious with the extension of time. Evaluating the cultivated land quality
change caused by the land consolidation could realize the comprehensive management of the cultivated land quality and
quantity. The results could be used as the basis of land consolidation work performance evaluation and provide
recommendations for future land consolidation research. |
