| description | The invention discloses a method for jointly evaluating a soil combined pollution ecological risk based on multiple organisms and multiple factors, and relates to the technical field of soil ecological risk evaluation. Comprising the following steps: sampling surface soil samples of soil in a risk evaluation area according to a five-point mixing method, and observing whether surface organisms of the soil exist or not, the types and the number of the organisms and whether irritating odor exists or not while sampling; the collected earth surface soil sample is used for carrying out toxicological tests of various organisms and carrying out physical and chemical properties of the soil; the soil ecological risk is jointly evaluated based on the combination of a soil field investigation result, a laboratory toxicological test result and a soil physicochemical property analysis result; and the assignment range of each index and the total risk grading of the combined ecological risk evaluation is stipulated. The soil |
