本研究的目的是考察土耳其安塔利亚省温室蔬菜生产中投入和产出的能量当量。为此，采用问卷调查的方式收集了88个大棚农场4种大棚作物（番茄、黄瓜、茄子和辣椒）的生产数据。结果表明，在四种作物中，黄瓜的生产是最耗能的。黄瓜生产消耗了134.77 GJha−1，其次是番茄，为127.32 GJha−1。茄子和辣椒的能量消耗分别为98.68和80.25 GJha−1。温室番茄、辣椒、黄瓜和茄子的产出投入能量比分别为1.26、0.99、0.76和0.61。这表明温室蔬菜生产投入的密集使用并没有伴随着最终产品的增加。这可能导致与这些投入有关的问题，如全球变暖、养分负荷和农药污染。因此，有必要推行一项新政策，迫使生产者采取能源效率高的做法，在不减少自然资源的情况下增加产量。
The aim of this research was to examine the energy equivalents of inputs and output in greenhouse vegetable production in the Antalya province of Turkey. For this purpose, the data for the production of four greenhouse crops (tomato, cucumber, eggplant and pepper) were collected in eighty-eight greenhouse farms by questionnaire. The results revealed that cucumber production was the most energy intensive of among the four crops investigated. Cucumber production consumed a total of 134.77 GJha−1followed by tomato with 127.32 GJha−1. The consumption of energy by eggplants and pepper were 98.68 and 80.25 GJha−1, respectively. The output–input energy ratio for greenhouse tomato, pepper, cucumber and eggplant were estimated to be 1.26, 0.99, 0.76 and 0.61, respectively. This indicated an intensive use of inputs in greenhouse vegetable production not accompanied by increase in the final product. This can lead to problems associated with these inputs such as global warming, nutrient loading and pesticide pollution. Therefore, there is a need to pursue a new policy to force producers to undertake energy efficient practices to increase the yield without diminishing natural resources.
