In the past 50 years, some irrational activities of land use
have made some ecological space maintaining regional ecosystem
health and safety destroyed which leading to a series of ecological
and environmental problems such as biodiversity reduction, soil
erosion, wetland destruction, and land contamination (Vitousek
et al., 1997).
The department of land management in China has not paid
sufficient attention to land functions that support and maintain the
stability of natural and artificial ecosystems (Xie et al., 2014). As the
increasing demand for construction land, ecological land in China
faces the threat of agricultural exploitation due to the land policy
“cultivated land requisition–compensation balance” (Xie et al.,
2014). Therefore, an urgent need to evaluate the ecological
importance of regional space and to develop some measures to
zoning control. This will prevent ecological issues bringing from
regional development and construction, guide regional planning
for sustainable development, and will carry out ecological
conservation and construction.
The main objectives are to evaluate the ecological importance of
space and to identify the ecological infrastructure (EI) maintaining
regional security and healthy of the land. Because ecological
infrastructure (EI) can provide sustainable ecosystem services for
residents, and it is the rigid restrictions inviolable by urban
expansion and land development (Maccagnani et al., 2013). In
essence, ecological infrastructure is the natural systems formaintaining regional sustainable development. A new comprehensive national land use plan in China (2006–2020) has clearly
outlined the requirements for eco-space, which will focus on the
overall arrangements for living, life and ecological space, protect
the productive land, give priority to the protection of natural
eco-spaces, and promote the development of regional ecological
civilization. Ecological civilization is a new concept proposed by
Hu Jintao and focuses on a list of elements including the right
relationship between man and nature.
