摘 要:采用野外实地调查、测量为主,图上量算为辅的方法,对济源城区的绿地现状进行了分析。结果表明,济源市城区绿化覆盖率为31.39%,绿地率为24.85%,绿化覆盖率略低于全国平均水平,远远低于全国12个园林城市的平均水平;人均占有绿地面积虽然高于全国城市人均绿地平均水平,但许多绿地都属于防护绿地或居住区绿地,而非真正意义上的公共绿地。从绿化率和人均绿地量来看,双桥区最高,北海区次之,天坛区第3,济水区最低。By using field survey and measurement as the main method and the measurement on the map as the assistant method, the current status of Greenland in the urban area of Jiyuan city were analyzed. The results showed that the green coverage in the urban area of Jiyuan city was 31.39% and the greenland rate was 24.85%. And the green coverage was slightly lower titan the national average level and greatly lower than the average level of 12 garden cities in China. Though the average greenland area per capita in Jiyuan city was higher than the average urban greenland level per capita in China, a lot of greenlands belonged to the protective greenland or greenland for residential area and they were not public greenlands. The green rate and greenland quantity per capita in Shuangqiao district was highest, followed by Beihai district, the third was Tiantan district and that in Jishui district was lowest.
