Abstract:: Taking runoff plots with different water conservation measures in Beijing Yanqing County Soil and Water Conservation Demonstration Garden as a case, the research on the influence of water conservation measures on the soil water-stable aggregates was carried out. Results showed that: (1) applying only engineering measures would break the soil water-stable aggregates, especially those with the particle size of 5~8mm, and it also reduced the water stability of soil aggregates, however, soil water-stable aggregates significantly increased, especially those with particle size of 2～5mm and 5～8mm after applying vegetation measures, it also improved the water stability of soil macroaggregates; (2) soil organic matter significantly promoted the formation of soil aggregates. The content of organic matter was obviously associated with both the content of soil water-stable macroaggregate and the water stability of soil macroaggregates. The result can provide a reforence to soil and water conservation study.
