摘要: 本文对作者《华南坡地利用与改良:重要性与可行性》一文在三个方面作一些补充:1.进一步阐述坡地的重要性,并特别从可能出现的全球性变暖的因果加以说明。2.对前文所提坡地改良与利用方针概括为:"主要采取植物(生物)措施,最大限度地提高以一个坡面或小流域为单位的坡地持续生产力",并对此作此较系统的论述。3.在前文基础上补充有关科研工作的意见。

关键词: 坡地利用与改良, 华南

Abstract: The problem under consideration is further discussed under three sections.In the first section,the economic significance of slopelands in South Chins is re-examined in the light of additional information.Special reference is made to the possible reduction of arable laad resulting from the rise of sealevel that may occur as a consequence of global warming.The present productivity of land on the slopes of hills and mountains is very low.Higher productivity will no doubt lead to a decrea.se of CO2 in the atmosphere.As the slopes are mostly well drained,the generation of other "greenhouse" gases can be easily kept to a minimum.

Key words: slopeland utilization and amelioration, South China
