Mangrove planting strategies should consider the optimal ratio between the area of tidal flats and the area of mangroves

Many countries, including China, have increased new areas of mangrove plantations to reverse the decline in ecosystem functions. However, this has led intrusion mangroves into many tidal flat areas, which are important habitats for shorebirds. A reduction available will reduce diversity shorebirds, therefore bringing conservation conflict with shorebird conservation. In fact, a certain area is an indispensable element habitat. Therefore, study proposes maintenance ratio between flats and within optimal both This recorded data distribution, flats, other relevant Guangdong Province, China. The ratios ecosystems were established mathematical model was applied establish relationship abundance areas. results showed that: (1) there no significant correlation richness (r = 0.176, p 0.230)and abundance(r 0.104,p 0.481), whereas richness(r 0.153, 0.299)and −0.063,p 0.670); (2) [x] [f(x)] [g(x)] satisfied cubic function equation f(x) 0.106x3−2.147x2+11.269x(0.0265≤x ≤ 13.8100) (R2 0.714, P 0.000),g(x)=0.008x3−0.189x2+1.124x (0.0265≤ x 0.713, 0.000); (3) appropriate value 3.5662or 3.9785, maintaining can promote sustainable development ecosystem. information contribute planting management strategies at various scales be invaluable assessing effectiveness existing approaches.
