史文娇 高标准 农田综合效益评价 空间预测 科研成果
2020/8/24
建设高标准农田是巩固和提高粮食生产能力、保障国家粮食安全的关键举措。近年来，我国大力推进高标准农田建设，取得了明显成效。因此，开展高标准农田综合效益评价及其空间尺度预测研究，能够为我国未来高标准农田建设布局、优化管理及战略决策提供科学依据和支撑。近期，史文娇等以我国重要的粮食主产区之一黄淮海区为研究对象，构建了包含经济、社会、生态效益的综合效益评价指标体系及综合评价模型，对黄淮海区高标准农田抽样项...
黄土区农草混合利用坡面土壤水分空间变异性（Spatial Variability of Soil Water Content on a Cropland-grassland Mixed Slope Land in the Loess Plateau, China）
土壤水分 农草混合结构 空间变异性
2010/12/29
通过对黄土区农草混合利用坡面的土壤水分分析，研究土地利用结构对土壤水分空间变异特性的影响。结果表明，研究区坡面土壤水分呈中等变异，且农草混合利用结构明显增加了土壤水分的空间变异强度，坡面土壤水分具有明显空间结构性。干湿条件下坡面0～60cm土层平均含水率的半方差最优理论模型分别为高斯模型和球状模型，且干旱条件较湿润条件下保持较高的基台值和变程，而块金值/基台值相对较低。Kriging插值结果显示...
