摘要
初步探讨了嘉陵江流域南充段生态系统多样性、野生动植物多样性在近几十年间的动态及现状，表明本区野生动植物多样性不高，且不断下降的趋势，有关本底资料缺乏，亟待进行详细的研究与及时保护．
A preliminary study on the dynamics of biodiversity in the middle reaches of the Jialing River (Nan-chong region) in the last decades is carried out. The result is shown that this region has relative low biodiversity,and thislow biodiversity is declining due to intensive activities of mankind. Up to now, there is lack of detailed data on the biodiversity of the region, investigation on the exact data of the regional biodiversity and it's protection should be carried out urgently.
