1. The land-use standards in the towns of Tianzhu and Renhe are
the highest in Shunyi, because electrical and transport manufacturing
with highest land-use efficiencies of all sectors in
Shunyi was planned to site in these towns. Furthermore, the
land-use standard of Tianzhu arranged for electrical product
is higher than Renhe arranged for transport product.(Fig. 1). The standard is based on gross
output per area.
