The analysis of the results of land reclamation technologies indicates that the technology of deep-digging and shallow-filling using pulp pump is not applicable in farmland restoration while the technology of deep-digging and shallow-filling using towed scraper is ideal at present .

对此，通过对土地复垦工艺效果分析，表明泥浆泵挖深垫浅复垦工艺不适宜在耕地恢复中应用，目前 拖 式 铲运机挖深垫浅工艺比较理想。

In comparison with other land reclamation technologies the land reclamation technology with the towed scraper has a quick travel speed higher efficiency a shorter construction period and other advantages . The reclamation technology has obvious time and economic benefits .

与其它复垦工艺相比， 拖 式 铲运机复垦技术具有速度快、效率高、工期短的优点，在土地复垦过程中发挥出明显的时间效益和经济效益。

The soil compaction of towed scraper reclamation and un-reclamation land gradually enhances when the depth increases .

铲运机复垦的 田块和未复垦的田块，压实度随着深度的增加，压实度逐渐增加。
