摘要

对开发建设平土区（未采取水保措施）的水土流失等级划分及其侵蚀模数确定进行了较为系统的研究，其等级划分标准与传统的农林水土保持截然不同。通过大量调查和试验测试，主要对花岗岩亦红壤形成的平土区的侵蚀模数进行了分析。结果表明，平土区的侵蚀模数严重级的一般在２～６万ｔ／（ｋｍ２·ａ），更严重的可达１０万ｔ／（ｋｍ２·ａ）以上。系统研究平土区的侵蚀模数尚属首次，可为城市水土保持工作（包括规划）提供科学的基础数据。

Abstract

This paper made a systematic researches on the determination on the level of soil and water loss in leveling area of development and construction (not being adopted the measurement of soil and water conservation). The determination of criteria of the level of erosion in urbanized development area is different from that of traditional soil and water loss in countryside. Through a large scale of field investigations and experiments

we analyzed the erosion modulus in leveling area correspondent with the characteristics of development area (including the soil type

this paper mainly research the area making up of red granite soil)

and the results showed that the soil erosion modulus in serious level of leveling area is average 20 000~60 000 t/(k㎡.a)

some erosion modulus may be up to more than 100 000 t/(k㎡.a). The paper reports the results of systematic research on the determination on the level of erosion and erosion modulus in construction development area first time. These results have provided the planning of soil and water conservation in Shenzhen City with scientific basic data

and it will be helpful for the work of soil and water conservation in other urbanized area.
