The results showed that during the research period,the fractal dimensions of paddy fields,dry land and wet areas increased obviously,whereas for forest land,shrubbery land and grass land,the fractal dimensions decreased.For all types of land,the values of landscape diversity index and landscape apartness index have increased but landscape dominance index value has rather decreased.Meanwhile it was found that the relation between fractal dimension and landscape fragmentation index showed significant positive correlation.

The results showed that fishes of 11 orders, 18 families, and 46 species were represented in Changshu section of the Yangtze river. After the season, the total catch per unit effort increased sharply in the section; the dominant species were mainly commercial fishes such as Coilia ectenes, Mugil cephalus and Parabramis pekinensis and the annual change of dominant species was not obvious. The CPUE of Coilia ectenes had risen up and the trend of resource deterioration had been kept within limits. The caught rate of pintsized and juvenile fish rose markedly. The Margalef's index and Wilhm's index had an evident tendency of rising, while McNaughton's index and Pielou's index waved slightly.
