Green Infrastructure

Planning should take precedence over the development of green spaces. In many previous plans, it was treated as an unused land. Although the many countries published law of ecological resources protection as well as a series of rules, due to the lack of legal supports for planning, causing that the ecological protection is usually neglected in the process of economic development and city expansion.

I believe the core idea of green infrastructure planning is the comprehensive social, economic and ecological benefits. Try to analyse existing and future land which is available, and then find out the suitable land for the protection and other land which might be suitable for development, at the same time, maximize the promotion of development and utilization of land resource. Green land could makes contribution on the process of achieving social, economic and environmental sustainability.To conclude, to develop the economic, social functions and benefits of green assets, it is necessary to plan at first, then distribute the land, and last execute the plan. Only in this way can we protect the land resources and reduce the risk of the erosion of natural ecosystem by the urbanization process. It also provides a very effective solution for the protection and development of land.
