中文摘要：潮沟网络是红树林湿地物质输运、水文调节及生态功能的重要组成部分,其时空演化对生态系统的稳定性与管理具有重要意义。本研究基于1986—2024年海南东寨港红树林自然保护区的Landsat影像,通过目视解译分析潮沟网络的时空分布与演化特征。结果表明,一级潮沟主导整体网络格局,其扩展或收缩决定系统结构的演变方向。潮沟演化过程可分为退化期(1986—1995年)、低位波动期(1995—2013年)和恢复期(2013—2024年)。潮沟系统稳定性与区域面积呈正相关,与养殖干扰呈负相关,对人类活动的响应受养殖干扰强度与区域面积的共同影响。气温和外海波浪动力是潮沟发育的主要自然驱动因素,植被扩展抑制潮沟复杂化;降水虽在统计上影响不显著,但其环境依赖性可能产生双重效应。总体而言,东寨港潮沟的演变是自然动力与人类干预共同作用的结果,其空间异质性体现了生态修复效应与环境条件的交互调控,为潮沟保护与红树林湿地管理提供了科学依据。

外文摘要：The tidal creek network is a vital component of material transport,hydrological regulation,and ecological functioning in mangrove wetlands,and its spatiotemporal evolution plays a key role in ecosystem stability and management.Based on Landsat imagery from 1986 to 2024 of the Dongzhaigang Mangrove Nature Reserve in Hainan,this study employed visual interpretation to analyze the spatial distribution and temporal evolution of the tidal creek network.Results show that primary creeks dominate the overall network configuration,and their expansion or contraction determines the system’s structural evolution.The evolutionary process of tidal creeks can be divided into a degradation stage(1986–1995),a low-fluctuation stage(1995–2013),and a recovery stage(2013–2024).The stability of the creek system exhibits a positive correlation with regional area and a negative correlation with aquaculture disturbance.At the same time,its response to human activities varies with the combined effects of aquaculture disturbance intensity and regional area.Air temperature and offshore wave dynamics are identified as the main natural drivers of creek development,whereas vegetation expansion inhibits creek complexity.Although precipitation is not a statistically significant effect,its environmental dependence may exert dual effects.Overall,the evolution of the Dongzhaigang tidal creek system results from the coupled effects of natural dynamics and human interventions.Its spatial heterogeneity reflects the interactive regulation between ecological restoration and environmental conditions,providing a scientific basis for the conservation of tidal creeks and the management of mangrove wetlands.
