The Yunlin coast: a first-level 18 protection area in mid-west Taiwan, was then used as an example to illustrate the proposed design 19 criteria. The safety of the present coastal defenses and land use of the Yunlin coastal area was 20 assessed, and coastal protection measures for hazard prevention were proposed based on the 21 generated risk map.

  • Agriculture Landscape Planning Based on Biotop Area Factor in Yunlin, Taiwan
    AGRICULTURE LANDSCAPE PLANNING BASED ON BIOTOP AREA FACTOR IN YUNLIN, TAIWAN Su-Hsin Lee1 and Jing-Shoung Hou2 1Professor, Department of Geography, National Taiwan Normal University NO.162, Heping East Rd., Section1, Taipei, Taiwan; Tel: +886-2-77341665 Email: [email protected] 2Professor, Department of Landscape Architecture at Tung-Hai University NO.20-5, Lane 128, Sec. 3 Chung-Gone Rd., Taichung 407, Taiwan; Tel: +886-4-24635298 Email: [email protected] KEY WORDS: landscape planning, agriculture, BAF ABSTRACT: Agriculture has been the primary industry in Yunlin area for hundreds years. It contributes to industrial and living landscape which continuously represents vivid cultural landscape of the area. The strategies of landscape planning in Yunlin area not only emphasis on improving landscape and environment, but also focus on sustaining agricultural culture through landscape planning. In addition, ecological consideration and adapt-for-environment land use guidelines should be applied for local environmental development in order to meet the goal of sustainable environment planning. In this case, Yunlin area’s local industries and economy can continuously develop in the process of landscape improvement considering social, economic, and ecological dimensions. The strategies demonstrate the concept of green infrastructure (G.I.). Therefore, this study uses biotope area factor (BAF) to analyse environmental resource of Yunlin area in order to contribute to agricultural landscape planning. The results show: 1)Yunlin area can be categorised into different sub-area of land use according to BAF. The categories include agriculture land, forest land, transportation land, water conservancy land, building land, public infrastructure land, recreation and leisure land, mining land, and the land for other use.

In this study, the PM2.5 and PCDD/Fs in the ambient air and the atmospheric dry and wet depositions were investigated in a coastal area of central Taiwan. During 2014, 2015 and 2016, the mean PM2.5 concentrations in Yunlin were 29.6, 26.6 and –3 26.3 µg m , respectively. The mean values of PM2.5/PM10 ratios were in an order of Lunbei (averaged at 0.55) > Taisi (averaged at 0.54) > Mailiao (averaged at 0.363). The modeled PCDD/Fs concentration at Yunlin were 0.0380, 0.0346 and –3 0.0324 pg WHO2005-TEQ m during 2014 to 2016. The observed concentration of total-PCDD/Fs-WHO2005-TEQ at –3 Yunlin in January and August were 0.089 and 0.00538 pg WHO2005-TEQ m , and the modeled concentration were 0.0598 –3 and 0.0176 pg WHO2005-TEQ m .

In 2017, the average dry deposition fluxes of total-PCDD/Fs-WHO2005-TEQ –2 –1 in various areas in Taiwan ranged between 57 (Lienchiang County in autumn) and 589 pg WHO2005-TEQ m month –2 –1 (Keelung City in winter), with an average of 221 pg WHO2005-TEQ m month . The average total deposition fluxes of total-PCDD/Fs-WHO2005-TEQ in various areas in Taiwan ranged between 65 (Lienchiang County in autumn) and 681 pg –2 –1 –2 –1 WHO2005-TEQ m month (Keelung City in winter), with an average of 263 pg WHO2005-TEQ m month . The fractions of dry deposition fluxes contributing to the total deposition fluxes ranged between 37.8% (Yilan County in winter) and 99.9% (Kaohsiung City in winter), with an average of 82.1%. This study provided valuable information for the control strategies of PCDD/Fs. Keywords: PM2.5; PCDD/Fs; Dry deposition; Total deposition.

  • An Assessment on the Ministry of Education's Air Pollution Prevention
    An Assessment on the Ministry of Education’s Air Pollution Prevention and Control： Strategies Proven to be Effective, School Children’s Health are Being Safeguarded (Courtesy of Qiu-Chan Qiu at the Division of Student Affairs and Campus Security) To envision effective and economically viable indoor and outdoor air pollution prevention and control strategies, the Ministry of Education has commissioned a team from the National Cheng Kung University to undertake a one-and-a-half-year project of "Planning, Implementation, and Evaluation of Effectiveness of School Air Pollution Prevention and Control Strategies" in May 2018. In particular, the “fresh air ventilation system” can effectively restore 100 percent of the indoor carbon dioxide to its standard value; the average rate of PM2.5 pollution in the classrooms with the system installed also improved as much as 70 percent. From October 2019, in response to the incoming season of severe air pollution (the autumn and winter seasons from October to March), a post assessment on the indoor air quality at school will be performed on a trial basis, and a complete report on the effectiveness of the implementation of the air pollution prevention and control measures will be put forward in early 1 2020 to persuade the Executive Yuan and the Environmental Protection Administration to implement the measures on a larger scale. To understand the effectiveness of this pilot project, Sun-Lu Fan, Political Deputy Minister of Education and Fu-Yuan Peng, Director-General of K-12 Education Administration of the Ministry of Education, led a team to the Yunlin County Yang Ming Elementary School on the morning of September 16, 2019 to observe the effectiveness of the school air pollution prevention and control strategies.

The Yunlin County located in the southwestern coastal region of Taiwan is one of the Received in revised form 9 August 2012 most counties with serious land subsidence because of the agricultural needs. In certain areas of the region, Accepted 9 August 2012 the subsidence rate reaches as much as 14.3 cm/yr. The severe land subsidence gives rise to the risk of flood Available online 18 August 2012 hazard and damage of infrastructures in this area. We represented a Persistent Scatterers InSAR (PSInSAR) results deduced from 1996 to 1999 time span for monitoring of land subsidence in this area. The PSInSAR Keywords: Land subsidence results show that Baojhou, Tuku and Yuanchang Townships reveal a maximum subsidence rate of about PSInSAR 7.8 cm/yr along the LOS and Lunbei Township located on the northern Yunlin reveals a subsidence rate of Precise leveling 3.5 cm/yr, which is quite coincident with the precise leveling result. This result has proven that the effective Groundwater pumping reduction of labor and cost could be achieved by using this technique on monitoring land subsidence in Natural hazards Yunlin County.

In addition, the seasonal distribution of six AQI classes and corresponding primary pollutants were further analyzed. The daily AQIs were 15–194 in 2015, 17–213 in 2016, and 16–184 in 2017, respectively. During the three year period, in the studied area, the mean proportions of levels with Grade I, II, III, IV, V, and VI were 3%–31%, 30%–57%, 17%–46%, 0%–12%, 0%–1% and 0% in spring; were 38%–76%, 21%–57%, 0%–10%, 0%–2%, 0% and 0% in summer; were 2%–45%, 34%–77%, 13%–36%, 0%–18%, 0% and 0% in fall, and were 0%–12%, 38%–67%, 24%–41%, 1%–22%, 0% and 0% in winter. Generally, it was found that summer has the best air quality and that winter has the worst, where spring and fall are similar in terms of air quality.
