  Biotope (habitat) type maps are essential as base maps for land use planning and biodiversity conservation. Actual vegetation maps are often used as the base maps, though important information for biotope evaluation such as vegetation structure and anthropogenic land modification is not shown enough. We proposed a procedure of biotope type mapping for rural areas and drew a prototype map. We classified biotope types following German system of biotope classification in some part and also considering soil moisture of rice paddies in winter, bank modification of irrigation canals, vegetation management frequency in grasslands and density of woodland understory.

In this study, we tried selection the index species in frogs and toads, because it was necessary to verify the relation with the population density of the index species and the ecological location type in rural landscape planning. The fauna composition and seasonal changes in the number of frogs was investigated by visual encounter survey and audio strip survey in hilly area, northern Kanto in 2006. Two species, Rana japonica and R. porosa porosa, has been selected as the index species for evaluation of the habitat quality. And the evaluation by the calculation value of yearlings should be low validity, and use the calculation value of adults. The suitable investigation season of two species for quantitative survey was clarified. In addition, it was shown that the presence of R. rugosa was able to become indices of various frog species composition when limiting it to the environment where the rice field existed.

We proposed a new consensus building method in a scene design of rural area, which consists of workshops involving pablic and image questionnaire by computer graphics (CG) to residents. The procedure is; 1) preliminary questionaire in a workshop to draw CG images, 2) image questionnaire to all residents in an area and 3) final workshop to make decisions of plans. As a result most participants in the workshop accepted the results of image questionnaires and were satisfied with the process.

ため池は本来の農業用水としての利用に加え, 近年では多様な生物を支える貴重な環境であることが指摘されている。また, 農業における管理作業は周辺の植物相に大きな影響を与えていると考えられる。そこで, 本研究では兵庫県北淡町のため池において, 農業における管理作業が植物相に与える影響について環境要因をとして明らかにすることを目的とした。管理については, 護岸の基質, 草刈り回数, 水位の変化, 環境要因に関しては, 気温, 水面の温度, 日射量, 土壌含水率, 植物相に関しては, 出現種および優占群落の調査を行った。その結果, 水位変化の影響を受けるため池周縁部下位で上位や提頂部と出現種が異なることがわかった。

The objective of this study is regional circulation of woody biomass. Taking account of the regional balance of supply and demand, this study aims to provide a utilization system to increase the use of woody biomass. The area designated for this study is Iwaki city and Kawauchi village of Fukushima Prefecture, Japan. The results are as follows. Judging from the supplied amount from the forest, approximately 40 times the amount of thermal energy from kerosene can be sustainably generated by using woody biomass. The pervasive eff ect on regional economy from the use of woody biomass can be estimated to be 13 hundred million yen in all and will make up 0.01% of Iwaki area's gross domestic production.

種の保存とランドスケープ－21世紀における自然と人との共生のあり方を考える。2008年には「種の保存とランドスケープ」というテーマに関わる大きな出来事が3つあった。一つは生物多様性基本法が6月に施行されたこと、次は国土形成計画（全国計画）が7月に閣議決定されたこと、そして3つめは、9月にトキの試験放鳥が佐渡島で実施されたことである。この3つの出来事が2008年にそろったことは偶然とも言えるが、2001年の環境省の発足以降、2002年の自然再生推進法制定、自然公園法改正、鳥獣保護法改正、2004年の外来生物法制定、2006年に再びの鳥獣保護法の改正、そして2007年11月に第三次生物多様性国家戦略が策定されるなど、近年種の保存とランドスケープを結びつけるような施策が展開されている。歴史。
