Abstract: Ecological potential of laudscape consists of its productive potential,ecological potential and priceless po-tential. Through calculating different productive potentials(photosynthetic potential,light-temperature potential,climatic potential and land potential）of agricultural and semi-natural landscapes in Dongling District of Shenyang,it is concluded that the photoutilization rate of crops in this district can be largedy increased.Soil fertility is the main limiting factor in improving agricultural production.Upland farming has the highest photo,utilization rate. The climatic productive potential of forest is higher than that of upland farming and lower than that of vegetable and rice production.This area should strongly develope the production of vegetables and increase the coverage of forest.

Key words: New Zealand, macroinvertebrate community index, quantitative macroinvertebrate community index, water quality monitoring.
