摘要

台灣自然災害頻繁。許多屬深山偏遠處之崩塌區，至今仍無法透過一般植生工法進行整治。無人機之相關技術日趨成熟，因此本研究將不同植生基材混合，製成三種植生粒劑，並針對不同粒劑之特性、發芽力進行分析，以選擇崩塌地適宜播種之粒劑。而結果發現，泥炭土植生粒劑之種子發芽力最高，但若考量材料成本、製作時間…等因素條件，則培養土植生粒劑較適宜於崩塌地進行播種。而植生粒劑經播種後發現，水份對粒劑之發芽生長具有直接影響。若環境缺乏水份，粒劑可於兩月內待降雨後逐漸生長。而環境水份充足時，粒劑可於四個月提升約15%之覆蓋率。因此，初步評估，崩塌地應用無人機播種植生粒劑進行植生復育，具有相當可行性。後續仍有研發推廣之價值。

In Taiwan, natural disasters occur frequently. Many landslides located in remote mountainous areas are still unable to be remediated by traditional engineering methods. The technology of unmanned aerial vehicles (UAVs) are maturing. Thus, this study aimed to identify vegetating pellets suitable for landslide remediation with UAV technology. Three kinds of vegetating pellets were made by mixing different vegetating materials and the germination of seeds in pellets was examined. Results have shown that the pellets made with peat soil are the best in terms of seed germination. However, when factors such as material costs, producing time are considered, the pellets made with culture soil are the best. The field trials showed that water determines seed germination of pellets. If the environment is lack of water, seeds in pellets remained viable for at least two months and could germinate after rains. And when the environmental water is sufficient, the pellets can increase the vegetative coverage by about 15% four months after sowing. Therefore, the preliminary trials showed that the method of using UAVs to sow vegetating pellets has considerable potential for the remediation of scattered landslides and is worth promotion and further studies.
