Problems solved by technology

Since the collection of sediment columnar samples requires a lot of manpower and material resources, and mangroves will deposit 1-3cm every year, if you want to systematically study the dynamic changes of phosphorus in mangrove sediments in a certain area, you need to periodically or Irregular collection of mangrove columnar samples will undoubtedly bring considerable tediousness and trouble to related re...

Embodiment Construction

[0066] The present invention will be further described in detail through specific embodiments below, but the embodiments of the present invention are not limited thereto.

[0067] Phosphorus cycle structure of candela mangrove figure 1 As shown, mainly including figure 2 The ecological process of candela shown and as image 3 Two parts of phosphorus cycling in candela mangrove sediments are shown. Among them, the ecological process of candela is an important factor in the phosphorus cycle of candela mangrove sediments. Candela grows through photosynthesis to absorb phosphorus in the sediment, and at the same time, the dead leaves of candela decompose and release phosphorus into the sediment. , thus affecting the change of phosphorus concentration in the sediment.

[0068] A method for simulating and predicting changes in total phosphorus concentration in candela mangrove wetland sediments, including:

[0069] S1. Construct the ecological process model of candela, includin...

Abstract

The invention belongs to the field of mangrove forest ecosystems, and relates to a method for simulating and predicting the total phosphorus concentration change of kandelia candel mangrove forest sediments. The method includes: constructing a kandelia candel ecological process model and a kandelia candel mangrove forest sediment phosphorus circulation model; the influence of the kandelia candel growth process on the kandelia candel mangrove sediment total phosphorus concentration is more accurately considered; on the basis of collecting and analyzing phosphorus elements in columnar sedimentsof the mangrove forest kandelia candel wetland, Model parameters are calibrated and a model is verified, and three methods of correlation analysis, root-mean-square error and observed value standard deviation ratio and consistency index are adopted to carry out precision analysis on the model, so that necessary theoretical reference and technical support are provided for research and management ofmangrove forest sediments.

Description

technical field [0001] The invention belongs to the field of mangrove ecosystems, and relates to a method for simulating and predicting the change of total phosphorus concentration in candela mangrove sediments. Background technique [0002] Mangrove is an evergreen shrub or arbor biome mainly composed of mangroves that grows in the intertidal zone of tropical and subtropical coasts. It is one of the most abundant, productive and complex ecosystems in the world. environmental and ecological value. As the interface between land and sea, the mangrove forest is an ideal place for absorption and storage of various substances due to its special geographical environment and complex root system. In recent years, with the development of the coastal zone and the rapid economic development of coastal areas, a large amount of pollutants have been directly or indirectly discharged into the ocean, which has aggravated the pollution of mangroves and further affected the coastal environme...
