摘　　要：城市土地利用方式的变化使生态系统的功能发生了改变,对城区的气候、水体、土壤及生物等产生了深远的影响.在土地利用结构的优化过程中采用生态绿当量理论,确定永川区的最低生态用地标准,研究发现:整个永川区达到最佳绿地覆盖率要求,但永川城区的用地需要重新进行规划,可以通过整个城区中心增绿,路林结合,构筑多功能、多效益、完整的城市发展生态网路,以达到提高城市绿地的面积或增加城市绿地质量的目的.Land use has not only changed the city underlying surface configuration,but also changed the process and function of ecological system,and more depth impact on the urban and regional climate,soil,water body and the biology.Ecological green equivalent principle has been introduced into the ecological optimization of the land utilization structure,and,according to the local natural resources and the present situation of the ecological environment to determine the city minimum ecological standard,the basic ecological city land has been ensured.In this article,from five aspects,such as atmosphere,water,soil,natural disasters and biological from,the ecological system of the play 17 kinds of ecological environment function has been listed in view of the different ecological system service,and different function score given.The results show that rural-urban continuum reaches the best green coverage requirements,but urban land use need readjustment.Therefore,it is necessary to control the urban construction land scale,to increase the urban green space area and to improve the quality of urban green space.
