VEGETASI MEMPERBAIKI KUALITAS UDARA KOTA

Vegetasi kota telah dikenal kemampuannya dalam memperbaiki kualitas udara kota dan mengurangi pemanasan udara kota.

Penanaman pohon telah digunakan untuk mengurangi fenomena pulau panas perkotaan, menyerap karbon dioksida, dan membantu untuk menjebak polutan udara pada daun.

Beberapa spesies tanaman mengemisikan senyawa organik volatil biogenik (BVOCs), penanaman beberapa kultivar meningkatkan ozon dan konsentrasi partikel ambien dan karenanya menurunkan kualitas udara.

Selain itu, serbuk sari dan spora jamur dari tanaman dapat membahayakan kesehatan bagi orang yang sensitif alergi .

Mmanfaat dan bahaya vegetasi kota terhadap kualitas udara perkotaan, dapat dianalisis dnegan simulasi komputer untuk memprediksi interaksi antara hutan kota dan lingkungan ambient. Untuk memaksimalkan efek menguntungkan lingkungan dari hutan kota, maka desain yang cermat, perencanaan, dan analisis biaya-manfaat harus dilakukan.
