Abstract: The average concentration of SO2 in the air of the park is lower than the national standard. The sulphur′s capacity of arbors is higher than that of the bush and the conifers′ is the lowest. The average quantity of SO2 pollutant of the trees in the park is 91.5% lower than in Dongling Park. Therefore,the park withought SO2 pollution is an ideal excursion and a contrast place for ecology study. Two methods determing the tree′s stress feature, injure and permibility, have the same results. Selection of planting trees in the city on their resistant to the pollution was obtained.

Key words: winter wheat, supplemental irrigation based on soil moisture measurement, water consumption characteristics, grain yield.
