Land Use Change and Its Ecological Effects in Ecologically Fragile Areas
, 2022 我国是世界上生态脆弱区分布面积最大、脆弱生态类型最多、生态脆弱性表现最明显的国家之一。生态脆弱区的生态环境保护是保障和维护国家生态安全的底线和生命线。然而，受人类不合理土地利用活动和气候变化的共同影响，我国生态脆弱区面临着植被破坏、土壤侵蚀、水土流失、水资源短缺等现实问题。全面认识生态脆弱区的土地利用变化及其生态效应，是优化土地利用结构布局和加强生态脆弱区生态保护的重要基础。 随着社会经济的快速发展，生态脆弱区土地资源的稀缺性日益显现；而土地利用结构的失衡更是加剧了生态脆弱区的生态环境退化 ...

Gaoya dianqi, 2022 针对电网电压出现不平衡会导致储能变流器（power conversion system,PCS）输出的有功功率波动、无功功率波动和三相电流峰值越限问题，文中提出了一种考虑电流峰值限制的储能变流器协调控制策略。首先分析了传统控制策略在电网电压不平衡下的局限性；其次利用瞬时功率理论与加权思想，在αβ两相静止坐标系上实现抑制有功功率波动与抑制无功功率波动的协调控制；然后在上述基础上，加入一种电流峰值限制方法，能在PCS进行协调控制的同时保障输出的三相电流峰值不越限 ...

基于InVEST模型的渭河流域干支流生态系统服务时空演变特征分析
Shuitu Baochi Xuebao, 2021 渭河作为黄河的最大支流，是生态保护建成区重点之一，对其生态系统服务研究有利于实现流域内高质量发展和生态保护之间的平衡关系，保持流域生态系统服务功能，促进流域生态系统恢复。基于InVEST模型分析渭河流域2000—2018年5期土地利用和干支流生态系统服务时空动态变化，采用相关性分析水源涵养、土壤保持和生物多样性之间的权衡和协同。结果表明：19年间，研究区土地利用情况主要以耕地、草地和林地为主，占总面积的95%以上。流域内水源涵养呈现"先上升后下降"趋势，平均栅格单元产水量542.9 mm ...
