It is 25 km away from the urban area, 19 km away from Tianjin International Airport, 14.5 km away from Tianjin Development Zone and 6 km away from Jingtang expressway The golden corridor connecting Binhai New Area. According to the overall planning of Tianjin, Jintang highway will be built as a special road for automobile. The planned light rail transit line, Jintang second line, Southeast ring line of railway and the special line of Tianjin Tiantie Coking Chemical Co., Ltd. will also pass through Wuxu street. The traffic conditions of Wuxu Street will be very convenient and fast. The superior location and convenient transportation provide a very favorable condition for wuzhuojie's foreign economic contact, science and technology, culture and information exchange, and also provide a strong attraction for wuzhuojie to raise funds for the development of export-oriented economy.

natural resources

The total area of the street is about 23.86 square kilometers, and the existing land is 35074 mu, including 30245 Mu within the boundary of wuxujie (including 11000 mu of large enterprises in China and 19245 mu of collective land), and 4829 mu of enclave outside the boundary. The village covers an area of 4938 mu, the enterprise covers an area of 2234 mu, the cultivated land is 5419 mu, and the other land is 6654 mu.

This area is a typical low plain landform, which is regressed from sea to land. The terrain is vast and flat. The altitude is below 2m, generally less than 1m. It is inclined slightly from west to East, and the ground slope is about 1 / 6000 ~ 1 / 10000. The ground is mainly composed of clay and sandy clay. The terrain is low and flat, mostly farmland. This area is located at the junction of Huanghua depression and Cangxian uplift. According to the regional geological data and seismic exploration results, the latest activity of Cangdong fault is from the late Middle Pleistocene to the early late Late Pleistocene, with little potential seismic risk. The soil property of bearing stratum is mainly silty clay and silt, the soil property of underlying stratum is mainly silt, and part of it is muddy soil. The thickness of muddy soil is generally less than 4m, the thickness of bearing stratum is generally more than 2m, and the roof elevation of bearing stratum is less than -0.5m. The better division is located in the Middle East of the planning area, and the general division is located in the West.

At present, the buried depth of water level in the fourth aquifer group has reached below 85m. At present, the annual maximum land subsidence is 54 mm, generally 20-30 mm. The main cause of land subsidence is groundwater exploitation, followed by consolidation settlement of under consolidated soft soil. According to the seismic damage investigation and exploration results, the eastern part of the planning area is the area where the saturated sand may liquefy. During the Tangshan earthquake, the sandblasting holes are often beaded, and there are often collapses and ground fissures in the section with large sandblasting volume.

Hydrological resources:

The shallow groundwater in this area is mainly phreatic water and micro confined water. The buried depth of groundwater level is 1.3-1.5m. There is no regional stable groundwater flow field, and evaporation is the main discharge mode. The hydrochemical type is cl Na type Cl.SO4 -Na type, non corrosive to concrete.

The deep groundwater is fresh water, which can be used in this area. At present, the water level of the fourth aquifer group is below 85m. The hydrochemical type is HCO3 Na type, and the salinity is less than 1.5g/l. After long-term exploitation, the groundwater level has dropped greatly, which has caused land subsidence.

The surface water in the area is mainly Haihe River, fish pond and open drainage channel. Haihe River flows through the south of wuxianjie, which is a first-class river. Shengli canal runs East-West in the middle of wuxia street, parallel to Jintang highway. Its main function is drainage.

Biodiversity: the region originally belongs to the farmland ecosystem. Due to the industrial development in recent years, it has gradually evolved into a landscape pattern with urban ecosystem as the main and farmland ecosystem as the auxiliary. However, the evolution process is short and the biodiversity is still rich.
