The calculation of ecological use of water resources is on the basis of eco-environmental investigation and analysis, and provides science foundation for reasonable allocation of water resources.

Integrating the predicting purpose of model and reasoning purpose of knowledge base system,a decision support system for greenhouse environment control was established as the goal of maximum ratio of output to input.

Method of environment control of greenhouse based on model was put forward.

Confronting with the lack of mushroom growth model and low environment control level for edible fungus industrial production, the appropriate environment conditions of Coprinus Comatus growth in the chamber and dynamic growth model based on temperature and humidity are studied.

By researching on the environmental in greenhouse and the control technique of the nutrient solution root system microenvironment, the environmental control mode based on the kind of cultivation mode was developed.

This paper study on the case of The Tropical Conservatory in Beijing Botanical Garden, the typical modern exhibition conservatory in China, includes the environmental control on the rainforest zone, the desert zone, the palm zone, and other zones.

An environmental performance management system for enterprises in eco-industrial parks was developed based on CCR model, a classical data envelopment analysis method, containing two important functions of performance evaluation and environmental regulation.
