Invest (Integrated Valuation of Ecosystem Services and Tradeoffs) is a set of model systems developed by the Natural Capital Project, for evaluating the quantity of ecosystem service functions and its economic value, supporting ecosystem management and decision -making.Including land, freshwater and marine ecosystem service evaluation models.The aim is to simulate the changes in the quality and value of the functional material and value of the ecosystem service function in different land use in different land, and provide a scientific basis for the benefits and influence of decision makers to weigh the benefits and influence of human activities.At present, the INVEST model developed by the natural capital project team has been widely used in environmental management decisions such as spatial planning, ecological compensation, risk management, and adapting to climate change in more than 20 countries and regions.In recent years, there have been more and more research on ecosystem services in India, and in the national, regional, and watershed ecological functional zoning, ecological protection red line delineation, ecological compensation, ecological protection and repair, carbon neutralization and other policiesApply.

INVEST model installation and GIS data processing 1.INVEST model introduction and installation; 2. collection and processing of preliminary data of theinvest model: realized in GIS software.

INVEST model-water production module

Data demand: The largest root system of the soil, annual precipitation, plant available water volume, the average annual potential steaming and distribution, the use of land use/coverage, the basin, the sub -widal, the biological physical coefficient table, etc.

INVEST model-soil keeping module

The soil erosion of the basin and the sedimentation of the sloping runoff of the slope is a natural process that determines the sand content of the runoff.The influencing factors of the sediment dynamics process in the water collection area mainly include human activities such as climate (especially the intensity of rainfall), soil, topography, vegetation, and agricultural production dams and other human activities.The main sources of rivers and sediment include the erosion of the watershed.

Invest model of nitrogen phosphorus output module

1 Principle of nitrogen phosphorus output model

In the model, the contribution of vegetation and soil to water purification is estimated by the ability to remove nutrient pollutants in runoff.Use data such as water production, land use, nutrient loading and filtering, and water quality standards to determine the nutrients and retention of current and future land use conditions.

The biological diversity of the Invest model, the quality module, the carbon fixed carbon module, and the city hot island relief module

1 Principles of biological diversity Habitat quality model principles

The HRA model can integrate information about the source of habitat exposure to each pressure source and the information of its exposure consequences to estimate and produce the risk chart of the production of life in the form of a single grid and regional scale.
