Abstract: In this paper,the gradient of soil Pb concentration (CK,100,500,1 000,2 000 mg／kg) was established by mixing Pb(CH3COOH)2 with soil and sand. The growth responses and resistance of four northern broadleaved tree species Acer ginnala,Pyrus ussuriensis,A. mono and Malus baccata to soil lead contamination were studied by growing their seedlings in pots in greenhouse.The results indicated that the seedling growth of all test species was enhanced under lower Pb concentrations (<500 mg／kg),including seedling height, ground diameter,leaf blade and the amount of new branches. With the increasing of Pb concentration, the growth became declined.Soil lead prevented the root system’s growth of most species.The changes of every index and difference between species were obvious. According to comprehensive analysis of above indices by using membership function,we could arrive at a conclusion that the P. ussuriensis had the strongest resistance of soil lead contamination,and next was A. ginnala, M. baccata, A. mono. Under the highest Pb concentration(2 000 mg／kg) the root of plant had the strongest enrichment of Pb,and the following was stem,leaf blade. P. ussuriensis had the stronger enrichment of soil lead than other three species.
