Air Quality: 　　Shanghai Seaport Comprehensivw Economic Development Zone has the best air quality in inland Shanghai. The Development Zone is adjacent to "Hangzhou Bay" in the south, and the Harbor enjoys clean sea breeze brought by 8-month's southeast monsoon every year. In the winter, owing to northwester, dusts in the urban will be baffled at the River by a "vapor curtain" generated by huangpu River. So the Development Zone has the best air quality in inland Shanghai, with dust laying quantity 10 percent of that in downtown. Terrant: 　　The terrain of Shanghai Seaport Comprehensivw Economic Development Zone features: The highest ground elevation of Shanghai. The Industry Area and its peripheral areas are the crustal upheaval of Shanghai, with average elevation above Zero Wusong by 4-4.5 meters and more than 1 meter above that of Shanghai. Flat surface relief. The Area is an alluvial plain of Yangtze Delta, with a single topographic from and flat surface relief. Good earth bearing strength of 15-20 tons/square meter. Stable climate: 　　Shanghai Seaport Comprehensivw Economic Development Zone is of typical subtropics monsoon marine climate, with air temperature between 37.9 and -7.1, the hottest month of July and August, the coldest month of January, and average temperature of 15.5, Annual rain day is 131 days, with average rainfall of 1089.2 millimeters.

Flood Tide: 　　It's recorded that the highest water level in one hundred years is 4.19 meters above "Zero" Wusong for Huangpu River, which is below 4.5 meters, the average elevation of the Seaport Development Zone. Earthquake: 　　The Zone has the extremely uncommon geological stratifications of Shanghai, with its lithosphere 180 meters below the zero line while the average of Shanghai is about -240 meters. The designed building earthquake resistance intensity of the Area is "6" degree on the Richter scale, one degree lower than that of its peripheral area Land smooth 　　The Land is natural and smooth, reaching at 4.0 meters high than Wusong absolute standard.
