• The authors analyzed three soil and water conservation measures : biological measures , engineering measures , tillage measures , which control the dissipative structure of soil erosion
  分析了控制土壤侵蚀耗散结构的生物措施、工程措施、耕作措施等三项水土保持措施。
• The dissipative structure about soil erosion cannot he engender , if soil and water conservation measures be collocated systematically and the soil grains reach to the balance inside system
  系统地配置各项水土保持措施，将使系统内土壤颗粒达到近平衡态，系统难以产生土壤侵蚀耗散结构。
• These models can be used to estimate impact of control measures on river runoff , and to what degree these measures effect the runoff production in river catchments at any given year
  该模型能分离水土流失综合治理对河川径流量的作用大小，并可估算任一年份水土保持措施对降雨产流量的影响程度。
