The invention particularly discloses an ecological city
system and a constructing method thereof. The ecological city
system comprises a city road net
system, a city rain seepage diverting and draining system,
crop planting belts,
forestry planting regions, industrial regions, commercial regions and residential regions. The city road net system comprises
pedestrian and non-
motorized vehicle lanes, and motor vehicle lanes are side-by-side arranged at the two sides of each
pedestrian and non-
motorized vehicle lane correspondingly;
crop planting belts are arranged at the outer sides of the two motor vehicle lanes; each industrial region, each commercial region and each residential region are arranged at the outer side of the corresponding
crop planting belt; and each residential region is located between the corresponding industrial region and the corresponding commercial region, and each
forestry planting region is arranged between the corresponding residential region and the corresponding industrial region. According to the city rain seepage diverting and draining system, the overall
water retention capacity of the city regions is increased, outstanding function for city
groundwater supplying is achieved, and city water resource is saved. According to the ecological city system and the constructing method thereof, region division of different functional regions of the city is reasonably planned, so that improvement of the city operation efficiency is facilitated, and mutual interferences between different regions are reduced.
