The experimental site is an indoor loess catchment that was constructed in a fixed-intensity rainfall erosion test facility. Nine high-resolution digital elevation model(DEM) data sets were gathered by close range photogrammetry during different phases of the experiment. To simulate the evolution of the catchment gully head, we assumed the following. First, the 5th and 6th DEM data sets were used as a data source for acquiring the location of the catchment gully head and for obtaining spatial variables with GIS spatial analysis tools. Second, the Fisher discriminant was used to calculate the weight of the spatial variables to determine the transition probabilities. Third, CA model was structured to simulate the evolution of the gully head by iterative looping. The status of the cell in the CA models was dynamically updated at the end of each loop to obtain realistic results. Finally, the nearest neighbor, G-function, K-function, Moran′s I and fractal indexes were used to evaluate the model results. Overall, the CA model can be used to simulate the evolution of a loess gully head. The experiment demonstrated the advantages of the CA model which can simulate the dynamic evolution of gully head evolution in a catchment.展开更多
文摘目的 观察头穴丛刺长留针法治疗偏头痛的临床疗效。方法 将88例偏头痛患者随机分为观察组(44例,脱落2例)和对照组(44例,脱落3例)。观察组采用常规针刺联合头穴丛刺长留针法治疗,对照组采用常规针刺方法治疗。比较两组临床疗效,观察两组治疗前后的视觉模拟量表(visual analog scale, VAS)评分、偏头痛特异性生活质量问卷(migraine-specific quality of life questionnaire, MSQ)、血清5-羟色胺(5-hydroxytryptamine, 5-HT)浓度。结果 观察组总有效率为92.9%,高于对照组的78.0%,差异有统计学意义(P>0.05)。两组治疗后VAS评分较治疗前降低(P<0.05),两组随访时VAS评分较治疗前和治疗后降低(P<0.05);观察组治疗后及随访时,VAS评分均低于对照组(P<0.05)。两组治疗后MSQ评分较治疗前升高(P<0.05),两组随访时MSQ评分较治疗前和治疗后升高(P<0.05);观察组治疗后及随访时,MSQ评分均高于对照组(P<0.05)。两组治疗后血清5-HT浓度均升高,且观察组高于对照组,差异有统计学意义(P<0.05)。结论 在常规针刺基础上,头穴丛刺长留针法治疗偏头痛临床疗效优于常规针刺方法,且在减轻偏头痛患者疼痛程度,改善其生活质量及提高5-HT浓度方面优于常规针刺方法。
