Knowledge sharing and green innovation are two key factors in shaping industrial sustainable competitiveness, and play a vital role in infrastructures’ transformation to sustainability. This paper, aiming at their collaboration among knowledge sharing, green innovation and infrastructures sustainable development, uses the relation structure in the measurement table to establish an interactively simulated model, which is verified and corrected by confirmed data from questionnaire. Knowledge sharing channel, behavior and environment promote the sustainable development of infrastructures, most contributed by knowledge sharing behavior. Green technical innovation and green system innovation play a positive role on the sustainable development of infrastructures, of which green technical innovation plays the bigger part. Three approaches, green technical innovation to knowledge sharing channel, green system innovation to knowledge sharing environment, green technical innovation/green system innovation to knowledge sharing behavior, play a mediating role in promoting the sustainable development of infrastructures. Green innovation may further boost the indirect impact of knowledge sharing on the sustainable development of infrastructures, but less from its direct impact. This paper presents suggestions on encouraging knowledge sharing behavior, setting up knowledge sharing system, constructing knowledge sharing environment for a sustainable development. Green collaborative innovation promotes the infrastructures. This paper provides theoretical references for a quality sustainable development of infrastructures.

This paper uses statistical and double wells power methods to estimate their geothermal resource of ten geothermal fields in Beijing and re-estimate their geothermal potential. The heatinfluencing range of double pumping-filling wells is 360k square meters at their space of 300m, which can hold 2.28 double pumping-filling units per square kilometer. The available heating potential will be 275 million square meters by statistical method, in Beijing’s ten geothermal fields under above conditions, and 301 million square meters by double wells power method. It could be up to 860 million square meters if geothermal graded using combined with other clean energy aids. Heating supply by using double wells system can increase well distribution density, helpful to promote the development of geothermal heating in Beijing, and in China.

The groundwater source heat pump system is one of the main ways of shallow geothermal resources development. This paper gives an introduction to HST3D code, which is widely used in China to simulate heat mobilization, and analyzes its advantages and disadvantages. Meanwhile, this paper discusses the application of HST3D code in heat mobilization simulation based on case study on underground water source pump engineering at Zhengzhou Children Hospital. This simulation analyzes the temperature changes in two wells in 8 years, of which the temperature increases no more than 1 Celsius degrees at No.3 well where is near the injection wells, and no more than 0.5 Celsius degree at No.6 well where is relatively far from the injection wells, consistent with real water temperature changes.

Based on the combination among land consolidation, the harmonious society and the essentiality of peasants involved in land consolidation during constructing harmonious society, this paper analyzes the present status of peasants involved in land consolidation in China, discusses the existing problems, and studies the basic frames for peasants to be involved in land consolidation in China.
