中国红树林湿地资源、保护现状和主要威胁
Resources, Conservation Status and Main Threats of Mangrove Wetlands in China
摘要
Abstract
Taking the second national survey (2009—2013) of wetland resources as an opportunity, by using CBERS-CCD data and other data, and combining the use of 3S technology and field investigation, this paper describes mangrove wetlands area in China and analyzes mangrove wetlands resources, conservation status and the main threats. The results showed that, (1) The overall Chinese mangrove wetlands area which rapidly decreasing from 42001 hm2 in 1950s to 22024.9 hm2 in 2000, and then rapidly increasing to 34472.14 hm2 in 2013; (2) From the provincial level, Hainan mangrove areas in recent years had remained relatively stable, but less than in 1950s, currently accounting for only 47.4% in 1950s; Guangxi and Guangdong mangrove areas in recent years had remained stable and had a certain growth, respectively restoring to the scale of 87.8% and 92.8% in 1950s; Fujian mangrove areas in recent years had maintained a stable growth, which had reached 1.6 times to the aera of 1950s; Zhejiang mangrove areas remained stable. (3) The mangrove protection system of China has been formed, including international important wetlands, national important wetlands, mangrove wetland nature reserve and mangrove wetland park, and the ecological condition of the mangrove wetland nature reserve and mangrove wetland park were good in general, which protected 77.7% of mangrove wetlands. (4) The main threats of mangrove wetlands in China included: pollution, land reclamation, excessively fishing and gathering, infrastructure and urban construction and invasion of alien species.关键词
