摘　　要：构建了保护性耕作适应性评价指标体系,利用该指标体系,可以快速评价免耕、浅松、深松、平作、垄作、碎秆覆盖、整秆(立秆)覆盖、整秆(倒秆)覆盖、留茬覆盖等关键技术的适应性等级与得分,根据适应性状况,区别独立方案和互斥方案两种不同条件,确定适合的保护性耕作模式。This paper established hierarchical system of suitability evaluation indices of conservation tillage, which is convenient to evaluate the suitability of no - tillage, surface - tillage, subsoiling, flatten - cultivation, ridge - cultivation, crushed stalk - mulch, whole stalk - mulch and stubble - mulch. According to the suitability of different techniques of conservation tillage, and distinguish the mutually exclusive projects and independent projects, the author conformed the suitable model of conservation tillage.

关 键 词：保护性耕作 适应性评价 模式选择方法 互斥方案 独立方案
