  • 지난 수십 년 동안 형태지수는 패치의 복잡성을 정량화하여 생물종 다양성 보존과 같은 경관생태계획에 활용되어 왔다. 지역계획 연구자들이나 정책결정자들에게 경관구조와 패턴을 정량화하는 경관생태지수는 대상지역을 모니터링할 수 있는 하나의 수단으로 활용되어 왔다. 그러나 경관생태지수관련 연구를 살펴보면 연구 목적 및 범위에 따라 활용하는 경관생태지수의 종류가 매우 다양하고 복잡한 것을 알 수 있다. 또한 연구목적에 적합한 경관생태지수를 선정하는 것은 복잡한 수학분석과 함께 많은 주의가 필요한 것을 알 수 있다. 따라서 본 연구에서는 형태지수들을 도시지역, 도시외곽지역, 농촌지역 그리고 산림지역 등 4군데 사례지역에 적용하여 그 결과를 통해 형태지수들의 특성을 살펴보았다. 그 결과, 평균형태지수값(MSI)에서는 도시외곽지역이 가장 높게 나타났고, 평균프랙텔차원지수(MPFD)에서는 농촌지역이 높게 나타났다. 넓은 면적을 가진 패치에 가중점을 고려한 평균형태지수값(AWMSI)과 평균프랙텔차원지수값(AWMPFD)에서는 산림지역이 가장 높게 나타났다. 사용한 네 가지 형태지수값의 순위가 4군데 사례지역에서 다르게 나타났다. 특히 둘레와 면적의 로그전환을 이용하고 있는 프랙텔차원지수들의 경우, 도시와 도시외곽지역의 MPFD값은 같고, 도시외곽지역, 농촌지역과 산림지역의 AWMPFD값 차이는 적어 순위 분별력이 떨어졌다. 따라서 넓은 면적을 가진 패치에 가중점을 고려한 평균형태지수(AWMSI)가 지역별 산림패치의 복잡성을 잘 정량화할 수 있음을 본 연구결과에서 보여주고 있다.

  • With the improvement of people's living standards and the development of tourism, tourists have greater freedom in choosing destinations. Therefore, as an indicator of satisfaction with scenic spots, tourist comments are becoming increasingly prominent. This paper aims to compare and analyze the landscape image of the Five Great Mountains in China and provide specific strategies for its development. The online reviews of tourists on the Online Travel Agency (OTA) website about the Five Great Mountains from 2015 to 2018 are collected as research samples. The text analysis method and R language are used to analyze the content of the tourist reviews, while the high-frequency words in the word cloud are used for visual display. In addition, the entropy weight method is used to determine the index weight and tourist satisfaction is evaluated to understand the weaknesses of those scenic spots. The results of the study show that firstly, the tourist satisfaction with the Five Great Mountains is basically consistent with its popularity. Secondly, through weight analysis, tourists pay special attention to the landscape features and environmental health of the scenic area, so that relevant departments should focus on building the landscape characteristics and improving the environmental health of the scenic area. At the same time, the accommodation and service management of the scenic spot cannot be ignored. Finally, according to the analysis results, suggestions are made on how to improve the tourist satisfaction with the Five Great Mountains.

  • We surveyed the vegetation of an ecological landscape preservation area (legally protected conservation areas or national parks) and the surrounding areas of Mt. Cheonggye, Republic of Korea, to explore the conservation implications for preservation areas and surrounding transition areas. We calculated diversity indices to identify the properties of the preservation and surrounding areas that are relevant to conservation efforts. We then compared the plant community composition between the areas using field and quadrat surveys in the preservation and surrounding areas. The cover of the dominant species in all tree and herb layers was markedly higher in the preservation area than in the peripheral zones. The species richness indices were significantly higher in the preservation area than in the peripheral zones. Ordination using detrended canonical correspondence analyses showed that the cover of the dominant tree species and rocks could explain the distribution of plant species in the Cartesian space of the ordination. Our results demonstrate that physiognomically designated protected areas match well with ecological data based on diversity indices and ordination analyses and that disturbances in the areas surrounding the ecological landscape of preservation areas can have considerable impacts on plant diversity indices. Hence, the preservation and management of surrounding areas are essential conservation elements for protecting the entire ecological landscape of preservation areas.

  • This study was carried out from June 1996 to November 1997 to analyze the growth characteristics of the introduced species revegetated on highway cut-slopes. The number of revegetation measures type surveyed were fourteen such as seed-spraying measures, block-sod pitching measures, and hydro-seeding measures with seed-fertilizer-soil materials. The introduced species for revegetation measures were mostly Festuca arundinancea(cool season grass), Eragrostic curvula(warm season grass), Lolium perenne(cool season grass), Dactylis glomerata(cool season grass), Poa pratensia(cool season grass). The species diversity index of the upper part on highway cut-slopes were greater than that of the middle part and lower part. The growth of introduced species was good on north-facing cut-slope than the others and that was flourish in temperate north forest zone. Also, the introduced species seemed to decrease or disappear, while the ratio of native woody and herb species which were in mature stage seemed to increase.

  • In this review, we present the results of our ten years of study on beef cattle production as a means of preserving phytodiversity and landscape in the semi-natural grasslands of the Aso region of Japan. There are about 16,000 ha of semi-natural grasslands in the region. The grasslands are maintained for animal production through such activities as grazing, mowing, and controlled burning. The Shannon's diversity index values, as measured in the present study, were higher in the grazed sites than in the abandoned sites. The grazing activities thus seem to create suitable habitats for coexisting herbaceous species. The grassland grazed moderately over a long term was able to sustain more animals than the grassland unused over a long term.
