矿山土地适宜性评价及复垦模式研究——以河南省重点煤炭基地土地复垦工程为例

以河南省重点煤炭基地土地复垦工程为例,分析了全省挖损地、塌陷地、压占地三大类待复垦土地现状,借鉴FAO的土地适宜性评价方法分别对三类待复垦土地进行了适宜性评价,以此测算出三类待复垦土地的复垦潜力,并进行了土地复垦潜力分区,最后总结出了集约化农业生态利用、果草林生态利用和农林渔禽生态利用三种土地复垦模式.

A Study of Land Suitability Evaluation and Reclamation of Coal Mining Areas——A Case Study of Coal Mining Areas in Henan Province

With the land reclamation project of the key coal bases in Henan Province as an example,this paper analyzes three kinds of land to be reclaimed,such as digging land,subsided land,geostatic land,and evaluates the suitability of the three kinds of land using the FAO land suitability evaluation method for reference.Based on this the paper measures the reclamation potential of the land and determines the land reclamation potential subareas,proposing three patterns of land reclamation,such as intensive use of agro-ecology use,fruit grass forest ecology use and agriculture forestry and fishing bird ecology use.
