The coastal ecosystem carbon pool estimation method of the invention belongs to the field of environmental assessment, and includes the following steps: (a) determining the spatial boundary of the coastal ecosystem; (b) determining the dominant plant classification area of the coastal ecosystem; (c) calculating the carbon source of the freshwater plant dominant area; (d) size setting of carbon source sampling point in coastal ecosystem; (e) sampling method of carbon source sampling point in coastal ecosystem; (f) carbon source estimation method in coastal ecosystem. The beneficial effects of the invention are as follows: a new method for classifying vegetation areas in coastal ecosystems by using dominant species is proposed, which reduces the difficulty of sampling and simplifies sampling steps; proposes a boundary division method for water body communication and carbon source calculation The method effectively fills the gap of the carbon source survey method in the estuary area; the proposed specific carbon source calculation method for tall shrubs and trees greatly reduces the difficulty and workload of the survey.

Estimation methods for carbon stocks in coastal ecosystems

A risk prediction and early warning method for water environments based on a water environment model predicting pollution discharge information for all pollution sources in a watershed, and including: selecting pollution sources requiring environmental risk prediction and early warning and dividing these into different risk prediction/early warning levels; determining from official environmental monitoring data and literature research initial elements for environmental pollution risk evaluation; obtaining principal pollution elements affecting pollution events; generating a plurality of environmental risk prediction and early warning models; forming a comprehensive fuzzy risk prediction and early warning model by combining the several risk prediction and early warning models having the best selective performance; inputting principal pollution element values into the comprehensive fuzzy risk prediction and early warning model, and predicting risk values for pollution events at pollution sources. The present method realizes prediction of watershed pollution risk, and resolves present deficiencies in watershed pollution risk prediction and early warning, while improving coverage rates for watershed pollution risk prediction and enhancing the accuracy thereof.

Water environment risk prediction and early warning method

A detection device for simultaneous in-situ measurement of dissolved oxygen at different submerged plant leaf-water interface levels. The detection device includes a dissolved oxygen micro-optrode host. A plurality of detection probes are externally connected to the dissolved oxygen micro-optrode host and can extend out probes. The detection device includes a leaf clamp having an upper clamping head, a lower clamping head, a hinged shaft and a clamping handle. Each of the upper and lower clamping head includes a plurality of water passing cavities penetrating through the back and the front thereof. Each of the upper and lower clamping head includes a plurality of slots horizontally extending inwardly of the corresponding clamping head. The detection device includes a plurality of insertion pieces having a probe groove. The detection probe is locatable in the respective probe groove for fixation. The insertion pieces are insertable and fixable in the slots.
