본 연구는 낙동강하굿둑 개방으로 인한 하구 인근의 식생 변화를 모니터링하기 위해서 현재 식생에 대해서 조사하고, 하구수변식생평가지수를 통해서 식생의 건강성을 평가하였다. 장기모니터링의 첫 번째 조사로 낙동강하구 인근의 6개 구역에 대해서 2021년 7월과 10월 2차례 수행하였으며, 식생모니터링 및 수생식물, 수변식물, 육상식물의 종조성, 분포밀도 조사를 진행하였다. 조사구역 내에서 확인된 관속식물은 82과 192속 230종 1아종 28변종 3품종 262분류군으로 파악되었다. KREVI를 통한 식생건강성 평가 결과는 1, 6번 구역이 두 차례 조사에서 모두 '매우 좋음' 등급이었고, 2, 4번 구역은 '매우 좋음'에서 '좋음'으로 2차 조사결과가 낮게 산정되었으며, 3, 5번 구역은 1차 조사에 비해 2차 조사결과가 1등급 상향되었다. 조사구역 대부분의 건강성 등급이 대체로 높게 평가되었다. 기수역 조성을 위한 수문개방 후 잠재자연식생의 대부분은 갈대군락으로 이루어질 것으로 예상되며, 수역과 인접한 버드나무군락의 경우 다소 면적이 좁아질 수 있으나 군락 형태를 유지하고, 염분농도가 매우 낮은 내륙지역 담수역의 경우 갈대가 대부분을 차지하며, 일부 물억새, 부들 등의 군락이 분포할 것으로 사료된다. 장기모니터링을 통해 이런 예상되는 변화를 관찰하며, 건강한 기수역이 조성될 수 있도록 하굿둑 개방 운영방안 등 대책이 수립되어야 할 것으로 판단된다.

Populations of plant-parasitic nematodes were evaluated in soil and root samples from areas planted with passion fruit, or covered with adjacent native cerrado vegetation, in five different cropping regions of the Brazilian Federal District. From July 2007 to January 2008, twenty samples had been collected in five Rural Centers (N$\acute{u}$cleo Rural-NR) planted with passion fruit. In five sites, samples were also collected in native cerrado vegetation. Specimens of nine genera of plant-parasitic nematodes (Meloidogyne, Helicotylenchus, Rotylenchulus, Scutellonema, Pratylenchus, Paratylenchus, Hemicycliophora, Xiphinema and Criconemoides) were found in the present survey. Important nematode pathogens, such as Rotylenchulus reniformis and Meloidogyne spp. were observed in the passion fruit plantations throughout five major producing regions of the Brazilian Federal District.

This study was conducted to investigate the plant community structure and to propose ecological management planning for the urban forest on Sungdongku, Joongku and Yongsanku in Seoul. Field survey was excuted October 1991 and the results were as follows. Robinia pseudoacasia community covered 61.1% and Populus x albaglandulosa covered 3.8% of survey site II and survey site was covered by the deciduous-broad leaf mixtured forest. According to the human impact and inappropriate management impact, survey area was divided into five forest community. As for the analysis of plant community structure which was classified into five forest community, the importance values, ecological diversity, number of species, number of individuals, basal area and crown coverage of the native plant community showed relatively higher than community that vegetation deterioration degree by the human impact showed seriously. In landscape forest of Mt. Daehyun, it showed problems for the planting method and the soil condition. So it was proposed to management guide, vegetation restoration and soil management through ecological management planning based on above results.

Vegetation structure of Jangtaesan Natural Recreation Forest in Daejeon City was investigated to suggest a preferable management plan. Vegetation survey was carried out with thirty plots. Adopting phytosociological method, plant communities were classified into twinfolds of natural and afforested area. A natural forest were composed of Quercus mongolica, Quercus variabilis, and Pinus densiflora community. Afforested area were with Metasequoia glyptostroboides, Larix leptolepis, Pinus koraiensis, and Castanea crenata community. The importance value of Quercus mongolica, Quercus variabilis, Pinus densiflora, and Quercus serrata in natural forest were 59.69%, 48.32%, 39.10%, 21.53%, respectively. According to diameter of breast hieght analysis results, it is expected that the occupancy of Quercus mongolica, Pinus densiflora, and Quercus variabilis would be continuously increased. Based on the findings of the study, management plan for natural forest and afforested area was recommended in line with the progress of natural ecology.

$CO_2$ uptake of vegetation is one of the important variables in order to estimate photosynthetic activity, plant growth and carbon budget estimations. The objective of this research was to develop a new estimation method of $CO_2$ uptake of vegetation based on airborne hyperspectral remote sensing measurements in combination with a photosynthetic rate curve model. In this study, a compact airborne spectrographic imager (CASI) was used to obtain image over a field that had been set up to study the $CO_2$ uptake of corn on August 7, 2002. Also, a field survey was conducted concurrently with the CASI overpass. As a field survey, chlorophyll a content, photosynthetic rate curve, Leaf area, dry biomass and light condition were measured. The developed estimation method for $CO_2$ uptake consists of three major parts: a linear mixture model, an enhanced big leaf model and a photosynthetic rate curve model. The Accuracy of this scheme indicates that $CO_2$ uptake of vegetation could be estimated by using airborne hyperspectral remote sensing data in combination with a physiological model.

The purpose of this study is to understand the vegetation structure of the Corylopsis coreana habitats in South Korea and their correlation with environmental factors, in order to provide basic data for preparing conservation. A total of 40 vegetation survey plots were established in around Southern region, Gangwon-do and Gyeonggi-do Province. The cluster analysis revealed four distinct clusters: Quercus mongolica-Pinus densiflora (QmPd), Castanea crenata (Cc), Quercus mongolica (Qm), and Pinus koraiensis (Pk). Among them, the QmPd cluster was selected as the representative community. Soil texture analysis that most areas consisted of loamy soil and were distributed on the northern aspects. The plantation, represented by Pk, exhibited a high content of exchangeable aluminum (5.227±0.342 mg/kg), suggesting the need for soil improvement and monitoring in these habitats. The canopy openness (forest gap) ranged from 11% to 21%, indicating a relatively closed canopy in many survey plots. Non-metric multidimensional scaling analysis indicated heterogeneous species composition between the QmPd cluster and the Pk cluster (total R² = 0.608).

A survey was conducted on the vegetation of Seogmo island, which is small island (ca. 41 okm2) located about 1km west of Kanghwa island in the central Korea, from Aug. 1983 to May 1984. Based on the field data, actual vegetation map and potential natural vegetation map were made. The island is covered with broad-leaved trees dominated with Quercus variabilis. The dominance diversity curves obtaiend in different associations are grouped in two types, lognormal distribution forms at the undisturbed vegetation and geometric series at the disturbed or rocky sites. It seems that the curves show to us the nature of their ecocline by the hypothesis of some investigators, i.e. Random niche boundary hypothesis, niche preemption hypothesis, lognormal distribution and logarithmic series. Total numbers of vascular plant species of the island were recorded 108 families, 348 genera, 475 species, 73 variaties and 7 forma. And Pte.-Q Index, 0.93, and Fisher's Index, 589.8, were higher than those in neighboring islands.
