中文摘要:
      【目的】掌握福建省耕地等别空间分布情况,对于制定合适的耕地保护决策以及合理地规划土地资源有着重大意义。【方法】本文以福建省84个县(市、区)的耕地等别评定成果为数据源,结合耕地保护评价分区成果,分析了全省耕地等别的空间分布特征。【结果】研究结果表明,福建省内无劣等地,耕地的平均等别为6.7等,高于全国平均等。全省耕地等别空间分布存在差异性,闽中谷地区,武夷山山地区,漳州市地区以及沿海部分地区的耕地平均等别高;闽西南部分地区,鹫峰-戴云山西北坡部分地区,鹫峰-戴云山东南坡的宁德市境内地区和闽东南山地丘陵地区的永春县等地的耕地平均等别低。结合福建省耕地保护网络化监管试点项目耕地保护评价结果发现,分布在中、差区的耕地面积占全省总耕地面积的50%以上,其中含有全省的75%的优等地。【结论】福建省耕地等别总体偏高,耕地等别的空间分异性受到自然条件和经济条件的影响,全省耕地等别存在下降的风险。
英文摘要:
      【Object】Understanding the distribution characteristics of arable land grade in Fujian Province is of great significance for making practical decisions about farmland preservation and for efficient arable land resource planning. 【Method】Considering the arable land grade assessment of 84 counties in Fujian province (including municipal district areas) as data source and taking full advantage of the result of regional arable land preservation, this paper analyzed the spatial distribution characteristics of arable land grade in Fujian province. 【Result】The results showed that there was no poor arable land in Fujian Province, whose the average grade was 6.77 and higher than the national average of 9.8. The average grade differences among counties,such as the average arable land grade of valley area,Wuyi areas ,Zhangzhou and the coastal were higher than others。According to the result of regional arable land preservation, cities got a rank C or D in preservation assessment turned to have a higher proportion of farmlands with superior quality, which may cause the trend of arable land grade decline in Fujian province.【Conclusion】The arable land grade of Fujian Province which has been affected by natural and economic conditions is on the high level, but risking of falling.
