摘要
通过对长春市主要绿地20块草坪3 a的跟踪观测,研究了长春市不同类型草坪能量和水分消耗状况.结果表明:高、中、低养护等级草坪的能量年平均消耗分别为9.97×105,3.34×105,1.57×105J/(m2·a),高养护等级草坪的能量消耗主要是喷灌,而中、低养护等级草坪的能量消耗主要是修剪;长春市草坪的平均耗水量为2.77 t/(m2·a),高养护等级草坪的耗水量为低养护等级草坪的11.8倍;草坪的能量和水分消耗在各月之间具有很大差异,能量消耗主要集中在6,7,8月份,水分消耗主要集中在5,6月份.
Through the observation of 20 lawns for three years, we have studied the consumption of energy and water of different types of lawns in Changchun city. The study showed that the energy consumption of high, medium and low maintain levels of lawns are 9.97 ×105 ,3.34 ×105 , 1.57×105J/（ m2 ~a） respectively, the main energy consumption of high maintain level lawn is watering energy, otherwise the main energy consumption of medium and low maintain level of lawns are pruning energy. The average water consumption of lawns in Changchun city is 2.77 t/（ m2 ~ a）, the water consumption of high maintain level of lawns is 11.8 times than that of low maintain level of lawns. The consumption of energy and water changed greatly among different months, the energy was largely consumed in June, July and Aug. and the main water consumption was in May and June.
