标准化降水指数（SPI）相比其他干旱指标有何优势？
What advantages does the Standardized Precipitation Index (SPI) have over other drought indicators?
SPI 仅基于降水概率分布进行标准化，能在不同气候区横向比较并区分气象干旱的时间尺度。它对数据需求低、计算简便，但忽略了蒸散与土壤水，故常与 SPEI 等结合使用。
SPI standardizes only the precipitation probability distribution, allowing cross-regional comparison and timescale-specific detection of meteorological drought. It needs little data and is simple, but ignores evapotranspiration and soil moisture, so it is often paired with SPEI.

参数化（指数型）灾害保险相比传统保险有何机制优势？
What mechanistic advantages do parametric (index-based) disaster insurance have over traditional insurance?
参数化保险在触发指标（如累积降雨量、风速）达到阈值即自动赔付，无需逐案定损，理赔快且交易成本与道德风险低。其短板是基差风险——指数与受灾户实际损失可能不匹配。
Parametric insurance pays automatically when a trigger index—such as accumulated rainfall or wind speed—crosses a threshold, with no loss adjustment, enabling fast payout and lower transaction costs and moral hazard. Its drawback is basis risk: the index may not match a policyholder's actual loss.

多灾种早期预警系统为何比单一灾害预警更高效？
Why are multi-hazard early warning systems more efficient than single-hazard ones?
多灾种系统共享观测、通信与指挥平台，能识别灾害链（如暴雨引发山洪与滑坡）并统一发布，降低重复建设与漏警。联合国倡导的「全民预警」目标正是推动此类系统在脆弱地区全覆盖。
Multi-hazard systems share observation, communication and command platforms, recognizing hazard chains—such as rainfall triggering flash floods and landslides—and issuing unified alerts, cutting duplication and missed warnings. The UN Early Warnings for All initiative promotes their coverage in vulnerable regions.

流域综合管理（IWRM）的核心原则是什么？
What are the core principles of integrated water resources management (IWRM)?
IWRM 以流域为单元，统筹地表水与地下水、水量与水质、供给与生态需求，并协调上下游与部门利益冲突。它强调利益相关方参与和适应性治理，避免割裂式治水带来的次生风险。
IWRM treats the river basin as the unit, integrating surface and groundwater, quantity and quality, and supply with ecological needs, while reconciling upstream–downstream and sectoral conflicts. It stresses stakeholder participation and adaptive governance to avoid unintended risks from fragmented management.

韧性城市理念如何整合灾害风险管理？
How does the resilient-city concept integrate disaster risk management?
韧性城市强调在灾前提升冗余与多样性、灾中维持关键功能、灾后快速恢复，把风险管理从被动防御转为主动适应。其核心是降低暴露与脆弱性并保障生命线系统的连续性。
Resilient cities build redundancy and diversity before disasters, maintain critical functions during them and recover quickly after, shifting risk management from passive defense to active adaptation. The core is lowering exposure and vulnerability while ensuring continuity of lifeline systems.

洪水风险地图通常基于哪些数据和方法编制？
What data and methods typically underlie flood risk mapping?
风险地图叠加历史洪水频率、地形高程与土地利用等图层，借助水力学模型模拟不同重现期下的淹没范围，再结合资产与人口暴露给出风险等级。其精度受地形数据与模型参数不确定性影响。
Risk maps overlay historical flood frequency, elevation and land use, use hydraulic models to simulate inundation at various return periods, then assign risk levels by combining asset and population exposure. Accuracy is limited by terrain data and model-parameter uncertainty.

城市不透水下垫面的扩张为何会加剧洪涝？
Why does expansion of impervious urban surfaces worsen flooding?
不透水面阻断雨水下渗、加快地表汇流并抬高洪峰流量与速率，使相同降雨下排水系统更易超负荷。结合湿地与农田的丧失，城市洪涝频率与强度显著上升。
Impervious surfaces block infiltration, speed up runoff concentration and raise flood-peak flow and rate, overloading drainage under the same rainfall. Together with lost wetlands and farmland, urban flood frequency and intensity rise markedly.
