摘要
【目的】通过对现行土地整治项目耕地差异的对比分析,探讨界定土地整治项目新增有效耕地的概念,构建测算小地物面积的数学模型,为土地整治新增耕地调查认定技术规范的出台提供理论依据和参考。【方法】采用文献资料分析、灰色系统GM(1,1)模型测算及遥感影像抽样样方调查。【结果】提出了土地整治项目新增有效耕地的概念,构建了测算小地物面积的数学模型。基于灰色系统GM(1,1)模型推算研究区中小地物面积占耕地面积比例为1.3%,新增有效耕地面积为13.31 hm^2,新增耕地率为8.27%,同时通过布设遥感影像抽样样方论证了小地物测算方法的可行性。【结论】新增有效耕地概念的提出更加符合土地整治中新增耕地认定和增加有效耕地的要求,GM(1,1)模型不仅排除了小地物对耕地面积的干扰,也使得土地整治项目新增有效耕地面积测算更加准确。
[Purpose]Our aim was to discuss the criteria for evaluating the new cultivated land and the effective cultivated land,so as to provide the theoretical basis for the introduction of the new technical evaluation of the cultivated land survey,based on the analysis of the present situation and existing problems of the newly increased cultivated land in the existing land remediation project.[Method]Literature research,GM(1,1)model and remote sensing survey according to the sampling frames were studied.[Results]We proposed a new cultivated land recognition criterion and a newly increased effective farmland concept.The calculation criterion is helpful for evaluating the newly increased cultivated land and the effective cultivated land.Based on the new effective cultivated land,the area of small area in the project area accounts for 1.3%of the cultivated land area,the new effective cultivated land area is 13.31 hm2,and the new cultivated land rate is 8.27%.[Conclusion]The concept of newly increased effective land more meets the requirements of effective arable land and the new cultivated land recognition standards in the land remediation in study area.The GM(1,1)model not only eliminates the disturbance of the small area to the cultivated land,but also makes the newly increased effective cultivated land area of the land improvement project more accurate.
