摘要

俄脚河小流域，因长期掠夺性开发利用，使植被屡遭破坏，生态环境恶化，加上落后的生产方式，造成粮食单产低，粮食产量严重不足。根据小流域的特点，通过科学配置各项治理措施，综合治理和控制水土流失，恢复生态平衡，改善粮食生产的外部生产条件，建设高标准的水平梯田，提高地力，改变传统的耕作制度，控制人口增长，大力推广良种和高产栽培技术，促进粮食的高产、稳产，为喀斯特地区解决粮食问题提供了较好的模式。

Abstract

In Ejiaohe small watershed

the productivity of grain is low and the total food production is seriously scarce because of the out-of-date mode of production as well as continuous destruction of vegetation and vileecotope resulted from long-term piratical exploitation.Based on the features of small watershed

scientifically configuring manag erial measures

synthetically handling and controlling soil and water loss

and recov ering balance of nature are necessary to improve the external condition of production. Developing high standard parallel terrace to improve the throughput of soil

changing tradi tional cultivation system and controlling the growth of population

and extensively spreading fine breed and cultivation technology of high production are needed to attain the high and stable productivity of grain. All above will provide a good mode to solute the food problem for carst areas.
