项目摘要

昨年度に踏査を行った調査候補地（沖縄県、福岡県、宮崎県、北海道）の内、沖縄県沖縄島北部の亜熱帯性常緑広葉樹林に設置された森林動態モニタリングプロットにおいて、樹木の動態パラメータ取得のための現地調査を行った。同調査地の過去２０年分の毎木調査データを分析し、樹種ごとの成長率と死亡率を推定した。樹木の繁殖特性と環境ニッチの関係性を、在来種と外来種で比較するために、福岡県の九州大学農学部附属演習林（福岡演習林）において、外国産樹種（ヌマスギ、Taxodium distichum）の種子散布・天然更新の状況を調査した。植栽地点の周辺約２㎞の範囲に渡って、実生の空間分布を調査した。このデータは、在来種と外来種間の環境ニッチの比較分析に用いる予定である。ミレニアムシードバンク（王立キュー植物園）の協力研究者と面談し、樹種ごとの種子の発芽特性情報の収集について、既存データの利用、追加情報の収集戦略について相談するとともに、将来的な国際共同研究テーマについて検討した。具体的には、本研究で得られる樹種ごとの環境ニッチ、繁殖特性、デモグラフィー特性の情報を統合的に用いることで、効率的かつ効果的な森林復元手法の開発に関する研究を検討した。

Last year, in the waiting area (Hokkaido, Fukushima, Miyazaki, Hokkaido), the forest was set up in the northern part of the city, and the forest dynamics was set up. In the past 20 years, the growth rate, growth rate and mortality rate of several kinds of trees have been estimated in the same city. The reproductive characteristics of tree trees are different in the environment, in foreign countries, in foreign countries, in the forest affiliated to the Department of Agriculture of Kyushu University, and in foreign countries. Several species of oysters (oysters, Taxodium distichum) distribute natural regeneration conditions. The space distribution of the planting site is about 2 square meters, and the space distribution of the planting site is about 2 miles. It is necessary to make a comparison between foreign countries and foreign countries in terms of environmental comparison and analysis. The cooperation between researchers and researchers in the field of plant research, the collection of information on bud characteristics of several kinds of plants, the utilization of existing drugs, the collection of additional information, and the joint study of international cooperation in the future. In this study, we have obtained the results of a variety of environmental studies, reproductive characteristics, characteristics of environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics, environmental protection, reproductive characteristics
