| Abstract: | 台灣欒樹（簡稱欒樹）富有四季變化，且於觀花、觀果上具有高度觀賞價值，普遍栽植於公園、校園、人行道等處，為國人所熟悉且深受喜愛的樹種之一。由於栽植數量頗多，導致近年來台灣各地民眾反應於欒樹週邊出現大量的紅姬緣椿象（簡稱椿象），並有椿象會飛入或爬進鄰近住家之情形，使得鄰近欒樹的住戶、行經路人深受困擾並造成恐慌。常有民眾反應要求移除欒樹，並於椿象大量出現時，噴灑藥藥劑以減少椿象之問題，但環保人士反對而造成爭議，讓相關單位無所適從。故本研究主要目的為探討欒樹對鄰近民眾造成之困擾及改善方式，包括對現有欒樹的處理與椿象大量出現時的改善方式。研究結果顯示椿象多於欒樹週邊活動，甚至群聚於人行道上，且欒樹與住商距離較短，椿象爬入住家之情形，確實造成受測者高度厭惡與害怕，而多數受測者見到椿象多選擇離開，若於室內發現，民眾普遍會將其送回欒樹週邊。受測者對椿象接受度與欒樹喜愛度對於見到大量椿象出現時之厭惡、害怕程度以及反應具顯著關聯。椿象接受度與椿象喜愛度越高者，對於椿象出現之厭惡、害怕程度明顯偏低，對於椿象出現之反應也較無特別反應，在欒樹的處理多認為保持現況即可，主要原因為不願意浪費公帑，且提供夏季遮蔭等。但仍有多數民眾希望可以將欒樹全部移植並更換樹種，因為欒樹除了引來椿象之外，亦有落花、落葉、落果與樹液之問題，認為欒樹雖富有四季不同之特色，相對而言，亦帶來四季不同之困擾，因此希望可更換較不具有爭議性之樹種，甚至反對再種植行道樹。與椿象大量出現時之改善方式上具有地區性之差異，且與人行道之規劃有相關，欒樹與住商家距離較近之街道困擾程度較大，故受測者多希望定時定期之噴灑藥劑與清掃環境以減少椿象之數量與躲藏之機會，而人行道寬度較寬之街道，椿象對於受測者之影響較小，因此該街道之受測者認為並不需要特別處理，應維持其生態平衡。經由本研究結果，普遍受測者希望以不破壞生態為原則，將其欒樹與椿象所造成之困擾降低。因此，建議相關單位日後需妥善規劃人行道與行道樹之選種，避免種植與住商家前，應將欒樹種於腹地較大之綠地空間，減少與住商家直接之接觸；針對現有欒樹與椿象應於椿象之繁殖期時，加強清掃環境減少數量以及躲藏之處以降低椿象所產生問題之可能性。
Koelreuteria formosana changes along the seasons with a high ornamental value in terms of the flowers and the fruits. It is commonly planted at the parks, schools, pedestrians, etc. and known as well as adored by the Taiwanese people. As the number of planting is quite large, people from different places have suggested the appearance of a large amount of Leptorcoris augur causing troubles and even panic to the neighbors as they fly around or break into the residences. Many of the residents have requested to remove the Taiwanese Rain Tree and to spray pesticide when there is a large amount of Leptorcoris augur as to solve the problem; however, many environmentalists have rejected the proposal and cause the controversy for which the authorities cannot do anything for it yet. Thus, this study aims to discuss the problems and the improvement methods caused by the Koelreuteria formosana, including the treatment to the existing plantations as well as the improvement methods when there is a large amount of Leptorcoris augur. The result shows that the Leptorcoris augur generally appear near Koelreuteria formosana or gather at the sidewalk and as the distance between the trees and the buildings are shorter, the phenomenon of the Leptorcoris augur at the residents would actually cause public’s disgust and fear. Most of the subjects opted to leave the room if Leptorcoris augur are found and most of the public would take them back near the Koelreuteria formosana. The degree of acceptance of the Leptorcoris augur and the degree of disgust and fear as well as the reactions towards them are significantly correlated. The higher the degree of acceptance and adoration towards the Leptorcoris augur, the lower the degree of disgust and fear would it be towards the Leptorcoris augur. They would not have any special reactions towards the appearance of the Leptorcoris augur and they wish to maintain the current condition for the treatment of the Koelreuteria formosana mainly because they do not want to waste the taxes and because the trees would provide a shading area during the summer seasons. However, most of the public opinion wishes to remove the Koelreuteria formosana and change the tree species, not only because of the Leptorcoris augur problem, but also of the flowers, leaves, fruits and the tree sap. They know that the trees have their own features during the four seasons, yet this may also represent different problems during different seasons. Thus, they wish to change the plantation into a less controversial species or even refuse to have other plantations. The improvement methods for the appearance of the Leptorcoris augur also vary depending on the regions, and they are mostly related with the planning of the sidewalks. Where the trees are closer to the buildings, the degree of trouble is higher, so the subjects hoped to have regular spraying of pesticide and cleaning of the environment as to reduce the number of Leptorcoris augur and the chances for them to hide. Where the sidewalks are wider, the influence of the Leptorcoris augur to the subjects are smaller, so the subjects believe that there is no need to treat the issue and the ecological balance should be maintained. Through this study’s results, the subjects generally wish to solve the problem caused by the Koelreuteria formosana and the Leptorcoris augur without damaging the ecology. Therefore, it is suggested to the authorities to have a careful planning of the sidewalks and the species of plantation. Plantations should be avoided in front of the buildings. Koelreuteria formosana shall be planted in larger green areas as to avoid close contact with the buildings. In terms of the breeding seasons of the Leptorcoris augur, environmental cleaning shall be stressed as to reduce the number of the bugs and their refugees which would then reduce the problems caused by them. |
