1引言我国是一个人口众多、土地资源有限的国家，人均占有耕地尚不到世界人均占有量的十分之一，人均占有土地只有世界人均占有量的三分之一。在经济建设中，人多地少是一个大矛盾，而且这个矛盾越来越尖锐。解决这个矛盾的有效途径之一就是充分利用各种废弃地，处理好高填土地 1 Introduction China is a country with a large population and limited land resources. Per capita arable land is still less than one-tenth of the world’s per capita possession. Per capita possession of land is only one-third of the world’s per capita possession. In the economic construction, the fact that more people and more people are fewer is a major contradiction, and this contradiction is becoming more and more acute. One of the effective ways to resolve this contradiction is to make full use of various abandoned land and deal with high-filled land.
