Live ecological damage and environmental pollution matters, such as major ecological damage, environmental pollution and sudden environmental events, the ecological Environmental status types to limit and adjust, see Table 5. Table 5 Environmental Restrictions Index Constraints Classification judgment based on the content of the constraint Sudden surroundings event Large environmental events in accordance with the "emergency response to environmental emergencies", district Domain caused by human factors caused by large, significant, Large or general level of sudden environmental events, If the evaluation area occurs more than one burst environment Incident, the most serious level prevail. Ecological environment can not be "excellent" and "good", and ecological ring Environmental quality level down 1 level. Major environmental events Large environmental events Ecological environment level down 1 level. General environmental events Ecology damage surroundings Pollution Environmental pollution The presence of environmental protection authorities notified of the country Home media coverage of environmental pollution or ecological damage The event (including the published environmental quality report Of the excessive area). There is environmental pollution that is notified by the Ministry of Environmental Protection Ecological damage events, the ecological environment can not be "excellent" and "Good", and the ecological environment level down 1; other categories Type of environmental pollution or ecological damage events, ecological ring Level level down 1 level. Ecological destruction Ecological environment illegal case The presence of environmental protection authorities informed or listed Supervised the case of illegal ecological environment. Ecological environment level down 1 level. Was included in the area limit Batch range By the environmental protection authorities into the regional limit approved Area Ecological environment level down 1 level. 5.9 Eco-environmental status grading According to the ecological environment index, the ecological environment is divided into five levels, namely, excellent, good, general, poor and poor, see Table 6. Table 6 Ecological environment status classification Excellent level is generally poor Exponent EI ≥ 75 55 ≤EI < 75 35 ≤EI < 55 20 ≤EI < 35 EI < 20 description Vegetation coverage High and diverse Rich, ecologically System stability. Vegetation coverage High, biodiversity Rich, suitable for people Class life. Vegetation coverage is medium and biological Kind of general level, more suitable for people Class life, but not suitable for humans The constraints of life appear. Vegetation coverage is poor and severe Drought, less species Less, there are obvious restrictions The factors of human life. Condition is more evil Bad, human beings Live is limited system. Analysis of Ecological Environment Change According to the changes of the ecological environment condition index and the reference value, the ecological environment quality change degree is divided into four levels, that is, Significant changes, good changes (good or worse), significant changes (good or worse), significant changes (good or worse). The sub-index changes Grading evaluation method can refer to the ecological environment changes in the degree of classification, see Table 7.
