Introduction

1. Basic concepts of wetland ecosystems

Wetlands are natural or artificial areas with significant ecological functions, including areas with perennial or seasonal water accumulation. According to GB/T 43624-2023, wetlands can be divided into natural wetlands and artificial wetlands according to their causes. The former include mangrove forests, while the latter include reservoir surfaces and pond surfaces.
