According to the complex and comprehensive characteristics of the content of the ecological environmental impact assessment, according to the latest guidelines for the ecological environmental impact Production of utilization map, production of vegetation type and vegetation coverage map, production of species suitable habitat distribution map, determination of biodiversity, determination of biomass and net primary productivity, determination of biological integrity index, calculation of landscape index, ecosystem type and Value assessment, general comprehensive index calculation of ecological environment status), and comprehensive use of ENVI, Rstudio, Fragstats and other mapping and analysis software to provide detailed explanation and practice for the completion of ecological environmental impact assessment investigation, analysis and report of different types of projects.
Topic 1: Specifications for Compilation of EIA Reports
Combined with the latest guidelines for ecological environmental impact assessment, the requirements and specifications for the preparation of ecological environmental impact assessment reports for different types of projects are described in detail.
Topic 2: Land Use Maps
1. Land use classification system
2. ENVI draws the status quo map of land use
• Image download: commonly used remote sensing image database
• Image correction: radiometric calibration, atmospheric correction
• Image cropping: regular, irregular, vector
• Unsupervised classification: ISODATA, K-Means
• Supervised classification: maximum likelihood, minimum distance
• Post-classification processing: filter analysis, Majority/Minority analysis, classification statistics
• Drawing production: ENVI Classic drawing, custom drawing elements
Topic 3: Vegetation types and vegetation coverage map
1. Vegetation type classification system
2. ENVI makes vegetation type map:
1) Data preprocessing: radiometric calibration, atmospheric correction, image cropping.
2) Classification method-decision tree classification: define classification rules, obtain thresholds (spectrum, NDVI, etc.), build decision trees, execute decision trees, and post-classification processing.
3. ENVI analyzes vegetation coverage: VFC = (NDVI-NDVIsoil)/ (NDVIveg-NDVIsoil)
4. Remote sensing mapping: generate mapping templates, customize mapping elements, and output mapping results
Topic 4: Species Suitable Habitat Distribution Map
1. Introduction to MAXENT maximum entropy model
2. Species distribution data collection
3. Environmental variable data collection
4. Prediction of species distribution area using Maxent model
5. Use R language to make species suitable habitat distribution map
Topic 5: Biodiversity Measurement
1. Biodiversity measurement in quadrats: process and requirements
2. Use R language to analyze and calculate biodiversity: calculation of α, β, γ diversity index, construction of species abundance distribution model
Topic 6: Biomass and NPP Determination
1. Biomass measurement: harvesting method
2. Construction of biomass model: single tree and stand biomass model
3. Use R language to build biomass models: regression analysis, regression diagnosis, optimal model selection (stepwise regression, full subset regression)
4. Vegetation Net Primary Productivity (NPP) Determination: Light Energy Use Efficiency Model (CASA)
Topic 7: Calculation of Biological Integrity Index
1. The meaning of Biological Integrity Index (IBI)
2. Construction steps of biological integrity index
3. Construction and screening of IBI candidate indicators: use R language for correlation analysis
4. Determination of IBI parameter value and health evaluation level: use R language to determine the 95% quantile

1. Ecosystem type and spatial pattern
2. ENVI analyzes and maps ecosystem types
3. The meaning, type and evaluation method of ecosystem service value
4. Equivalence factor method to assess the value of ecosystem services
Topic 10: General Comprehensive Index of Ecological Environment
1. AHP and its basic steps
2. Index weight calculation method: use R language to conduct principal component analysis and calculate weight
3. Construction of comprehensive index (EI) of ecological environment status: biological abundance index + vegetation coverage index + water network density index + land stress index + pollution load index + environmental restriction index
