| Abstract: | The ecological.benefits of shelter-forest adopting the combined methods are discussed,such as visual interpretatinn of remote sensing imagery with fieldsurvey, routine analysis of climate, geoscience correlation analysis and observation of shelter-forest microclimate in fixed area. The remarkable change of ecological environment, especially ecological benefit, has taken place since the shelter-forest project established in this area, and the mathematicial model is givenfor measuring ecological benefits. |
