在构思地块尺度耕地生态价值测算方法及测算调查水田、旱地地块生态价值的基础上,解析地块尺度耕地生态价值特征,识别耕地生态价值影响机理,构建促进耕地生态价值提升的综合措施体系。结果表明:耕地地块的复种指数、生物产量越高,其提供生态服务功能的能力越强;3个村水田、旱地地块生态价值均受到耕地质量指数和复种指数两个因子的显著正影响作用,具有价值提升空间。耕地生态价值提升应从加强土地整治工程的规划与实施、合理调整农户的耕作制度行为和物质投入行为、加强农业技术的研究与推广应用和大力推行生态农业4个方面综合践行。
在構思地塊呎度耕地生態價值測算方法及測算調查水田、旱地地塊生態價值的基礎上,解析地塊呎度耕地生態價值特徵,識彆耕地生態價值影響機理,構建促進耕地生態價值提升的綜閤措施體繫。結果錶明:耕地地塊的複種指數、生物產量越高,其提供生態服務功能的能力越彊;3箇村水田、旱地地塊生態價值均受到耕地質量指數和複種指數兩箇因子的顯著正影響作用,具有價值提升空間。耕地生態價值提升應從加彊土地整治工程的規劃與實施、閤理調整農戶的耕作製度行為和物質投入行為、加彊農業技術的研究與推廣應用和大力推行生態農業4箇方麵綜閤踐行。

On the basis of conceiving the calculation method of ecological value and calculating the surveyed cultivated land plots ’ ecological value , the ecological value characteristic of cultivated land at the plot scale was analyzed , the effect mechanism of ecological value of cultivated land was recognized , and the comprehensive measure system to enhance the ecological value of cultivated land was constructed .The results suggest that: the higher the multiple cropping index and biological production of cultivated land was , the stronger the ecological service function of cultivated land will be ;the ecological value of paddy field and dry field in the three villages was significantly and positively affected by the infield quality index and multiple cropping index , which shows that the ecological value of cultivated land can be further promo-ted;the increment of ecological value of cultivated land should be conducted on four aspects , which are strengthening the plan and implementation of land consolidation projects , adjusting farmer's farming system behavior and material invest-ment behavior reasonably , strengthening the research and application of agricultural technology , carrying out the ecologi-cal agriculture vigorously .
