复垦土地的适宜性评价是制订土地复垦方案的前提和基础,为合理复垦、利用待复垦土地资源提供科学依据。以阜新市彰武县冯家砖厂黏土矿为例,结合矿区自然条件及实际情况,将该矿复垦土地划分为相应的评价单元,并确定各单元主要破坏类型,参考林地适宜性评价指标,最终确定各单元用地的复垦方向。结果表明,各单元主要破坏类型为挖损和压占;各单元用地的复垦方向为林地。
複墾土地的適宜性評價是製訂土地複墾方案的前提和基礎,為閤理複墾、利用待複墾土地資源提供科學依據。以阜新市彰武縣馮傢磚廠黏土礦為例,結閤礦區自然條件及實際情況,將該礦複墾土地劃分為相應的評價單元,併確定各單元主要破壞類型,參攷林地適宜性評價指標,最終確定各單元用地的複墾方嚮。結果錶明,各單元主要破壞類型為挖損和壓佔;各單元用地的複墾方嚮為林地。

The suitable assessment of reclaimed land is the premise and basis to make land reclamation scheme for reasonable reclamation and using reclamation land resources to provide scientific basis.Taking clay mine of Fengjia brick factory in Zhangwu county of Fuxin city as an example,combining with the mining natural conditions practical situation,the mine reclamation land was divided into the corresponding evaluation units,and the major damage type of the units were determined.Referencing forest land suitability assessment indexes,the final of the land reclamation direction for each unit was determined.Result shows that the major damage types of the units are digging occupation;the direction of the land reclamation for each unit is forest land.
