项目摘要

"Kyoto Protocol to the United Nations Framework Convention on Climate Change" went into effect on February 2005, and Japanese government powerfully support the plant action to complete the engagement of decrease the emission of carbon dioxides. On the other hand,, because of numerous wind-break forests are cut year by year, the carbon dioxides is discharged into atmosphere from the tree in our country. In this research on the distribution of wind-break forests and pleasing effect on micro-climate in and around the forests in Sendai plain, we have some surveys as follows;(1) Distribution of wind-break forests : area (length, width, height), tree species and so on(2) Pleasing effects by forests on micro-climate : air temperature, wind speed(3) Purify effect of forest on air pollution : nitrogen dioxides nitric oxide and PM(4) Estimate of carbon dioxides mass in the tree : density of trees in unit area, CO2 mass in unit area(5) Decrease of wind-break forests : measuring of forests area on the air photograph, 1961-1999(6) Intention survey about the farm family : reason why cut the forest and the merits or demerits of wind-break forestAccording the research data, a lot of wind-break forests are existing now, but clearly decreasing at all of the Sendai plain because of the extending urbanized area of Sendai city, and total amount of forest area decreased about 40% in last 40 years, in the central part of Sendai plain. As the forests keep the carbon dioxides and have the effect on micro-climate or air pollution, it is important action what to keep and grow the forest. Most of alder parsons are tend to keep the forest, but most of younger families tend to cut and clear the house area. It is important to public support to keep the forests.

《联合国气候变化框架公约京都议定书》于2005年2月生效，日本政府大力支持植物行动，以完成减少二氧化碳排放的承诺。另一方面，由于我国大量的防风林被逐年砍伐，大量的二氧化碳从树木中排放到大气中。本研究对仙台平原防风林的分布及其对林内和林周小气候的调节作用进行了如下调查：（1）防风林的分布：面积（长、宽、高）、树种等（2）森林对小气候的宜人作用：气温、风速（3）森林对空气污染的净化作用：（4）树木中二氧化碳质量估算：单位面积树木密度，单位面积CO2质量（5）防风林减少：1961-1999年航空照片上森林面积的测量（6）农户意向调查：砍伐森林的原因及防风林的利弊根据调查资料，仙台平原目前存在大量的防风林，但由于仙台市城市化面积的扩大，近40年来，仙台平原中部的森林面积减少了约40%。由于森林对大气中二氧化碳的储存和对小气候或大气污染的影响，森林的保护和生长是一个重要的行动。大多数桤木帕森斯倾向于保持森林，但大多数年轻的家庭倾向于削减和清除房屋面积。公众的支持对保护森林很重要。
