中文摘要 文中以集沙池(集沙槽)法分别对干旱风沙区宁夏回族自治区盐池县典型退耕还林柠条灌木林地、樟子松乔木林地、旱作农田、放牧草地的近地表集沙量进行监测与评价。研究表明:旱作农田的年均总集沙量最大,为319 288.43 g,分别是樟子松乔木林地、退耕还林柠条灌木林地、放牧草地的241.43、351.88、1.96倍;旱作农田及放牧草地均是当地主要沙尘源,而退耕还林柠条灌木林地防风固沙效果最为明显。研究结果可为科学评价退耕还林还草工程生态效益提供技术支撑,对干旱风沙区生态修复有指导意义。

英文摘要 The near-surface wind erosion in typical forestland converted from farmland to forest, including Caragana intermedia shrub land, Pinus sylvestris var.mongolica forestland, rainfed farmland and grazing grassland in Yanchi County is monitored and evaluated using sand ponding method. The results show that rainfed farmland has the maximum annual average sand amount collected at 319 288.2 g, which is 241.43, 351.95 and 1.96 times of that of P. sylvestris var. mongolica forestland, C. intermedia shrub land and grazing grassland, respectively; rainfed farmland and grazing grassland are the main source of sand and dust in the study area, while C. intermedia shrub land has the most obvious effect in terms of windbreak and sand fixation. This study would provide technical backup for the science-based evaluation of ecological benefits of the forestland converted from farmland, which is of great significance for guiding the ecological restoration in arid sandstorm area.
