摘要

九寨沟以其罕见的自然美所赋存的“突出普遍价值”（OUV）被列入世界自然遗产名录，2017年“8·8”九寨沟

s7.0地震是继2008年“5·12”汶川特大地震后川西北地区遭遇的又一次强震，是我国遗产地内发生的首次强震，震后世界自然遗产地规模性治理尚无先例.本研究聚焦震后九寨沟地质灾害防治与地质环境保护重大需求，融入“基于自然的解决方案”（NbS）理念，在生态地质环境全要素调查、地质灾害发育分布规律解析、生态问题系统诊断基础上，（1）研发了水环境糯米石灰华胶凝材料（水下养护60 d抗压强度

12 MPa），构建了“振冲碎石桩固基‒糯米灰浆筑坝‒碳化竹锚护坡‒乡土植物绿化‒分形景观设计”的震损钙华坝生态修复技术，实现了钙华湖群原真保育；（2）创新了震损高陡岩质边坡崩塌灾害的“结构补强‒生态固土‒生物诱导”生态化治理技术，提出了大型松散堆积体滑坡与水土灾害的“阻渗‒植生‒结皮”生态位重构技术，治理后抗降雨冲刷强度

150 mm/h、水土流失量降低90%，实现了地质灾害治理与生态兼容；（3）提出了地质灾害“场地‒单元‒流域”多级调控技术，实现了震后地质灾害防治、生态地质环境保护、生态功能恢复协同增效，治理后土壤有机质、养分含量及生物量达到未扰区的90%；（4）跨学科考虑地质稳定、水土保持、生态恢复、景观融合等7个一级、13个二级、17个三级目标要素，构建了地质灾害生态化治理成效多维评估方法体系.本研究以期为九寨沟灾害防治、生境质量提升、生物多样性保护提供科学路径，为世界自然遗产地生态地质环境保护与可持续发展提供理论和技术支撑.

Abstract

The

s7.0 Jiuzhaigou earthquake on August 8

2017

struck the Jiuzhaigou Valley

a World Natural Heritage site. This event represents another significant seismic impact on Northwest Sichuan following the 2008 Wenchuan earthquake

the first within a Chinese heritage site. Listed for its “Outstanding Universal Value” (OUV) based on exceptional natural beauty

Jiuzhaigou faced an unprecedented challenge: managing regional-scale restoration within a World Heritage site after a major earthquake-A task with no prior domestic or international parallel. Based on a comprehensive survey of eco-geological environment elements

an analysis of geohazard distribution patterns

and a systematic diagnosis of ecological issues

this study focuses on the critical needs of post-disaster geohazard prevention and geological environment protection

integrating Nature-based Solutions (NbS). This study obtains the following results: (1) Developed a water environment-friendly glutinous rice lime travertine cementitious material that achieves a compressive strength of

12 MPa after 60 days of underwater curing; established an ecological restoration technology for damaged travertine dams using “vibro-replacement gravel piles for foundation reinforcement-glutinous rice mortar dam construction-carbonized bamboo anchors for slope protection-native plant greening-fractal landscape design”

successfully preserving the authenticity of travertine lake clusters. (2) Innovated an ecological approach for managing collapse hazards in steep rock slopes affected by earthquakes

combining structural reinforcement

ecological soil stabilization

and bioinduction; proposed a niche reconstruction technique involving “barrier construction-vegetation establishment-crust formation” for large-scale loose debris landslides and soil-water disasters; with rainfall erosion resistance

150 mm/h and 90% soil loss reduction

achieving effective integration between geological hazard control and ecological recovery. (3) Put forward a multi-level regulation technology for geohazards across “ site-unit-watershed” scales

realizing synergistic effects between geohazard prevention

ecological functional recovery

and eco-geological environment protection

and after treatment

soil organic matter

nutrients

and biomass reached 90% of undisturbed levels. (4) Constructed a multi-dimensional evaluation method

incorporating 7 primary

13 secondary

and 17 tertiary objectives

for the effectiveness of ecological geohazard mitigation by interdisciplinary integration of geological stability

soil and water conservation

ecological restoration

and landscape harmony. This research provides a scientific trajectory for disaster prevention

habitat quality enhancement

and biodiversity conservation in Jiuzhaigou

offering theoretical references and technical support for the protection and sustainabl

e development of eco-geological environments in World Natural Heritage sites.
