nder the guidence of the idea of landscape and the method of GIS, the author develops thespatial information database to be used to analyse patches, irregularity and general feature of landscape of forest vegetation in Fujian. It is shown that the complexity of toPOgraphy and disruptionsof mankind are primary physical parameters of controlling ecosystem functions of landscape(suchas motions of water and soil, rainfall and temperature), diversity of living things and efficiencyof soil water. The synthetical characters of landscape calculated reflect briefly the influences ofthose two physical paraneters. StructUre and shape of artificial vegetation (especially forpaddy) suit fundamentally to toPography. Both southern subtropical rainforest and middle subtropical evergreen broad-leaf forest exist at lower fractal dimension and simple geometrical Patterns. Their shapes are obviously different from these of toPography condition and structures ofothers landscape tares which are more complex. It indicates that human activities have produceddeep influences on the structure of the two zonality landscapes.The author shows spatial distribution of forest vegetation by GIS, surveys spatial strUctureof forest vegetation by quantitative models. From those it can be explained how the forest vegetation in Fujian is restricted by physical, biological, social and economic factors.

The distributional rule of canopy gaps of Larix gmelinii forests in Daxinganling, Heilongjiang Province, was studied using wavelet analysis. The results obtained are as follows: The optimum scale of wavelet transformation for estimating the percent of gap distribution in transect of forests is 10 meters. That for variable density of gap distribution is about 20 meters. The gap distribution in small areas of 20×20m 2 in transects is relatively stable and tends to be fragmental and discontinuous with increase...

The distributional rule of canopy gaps of Larix gmelinii forests in Daxinganling, Heilongjiang Province, was studied using wavelet analysis. The results obtained are as follows: The optimum scale of wavelet transformation for estimating the percent of gap distribution in transect of forests is 10 meters. That for variable density of gap distribution is about 20 meters. The gap distribution in small areas of 20×20m 2 in transects is relatively stable and tends to be fragmental and discontinuous with increase in altitude. It was approved that the wavelet analysis is an effective and credible method in the study on spatial pattern of vegetational distribution.

采用小波分析的方法对黑龙江省大兴安岭兴安落叶松林的林窗分布进行分析,研究结果表明:兴安落叶松林样带内计算林窗分布百分率小波变换的最佳尺度为10m 。林窗分布的疏密变化尺度为20m 左右,在样地中20×20m 2的小区域内具有较为稳定的分布特点。在样带中林窗分布呈斑块状,且斑块分布随样带的海拔的升高呈间断性分布。小波分析被证明是植被空间格局研究的简捷可靠的新方法。

According to landscape ecology,this paper discusses the characteristics causing silt in a watershed and relations between them and forest/grass vegetation.It is shown that soil erosion situation in a watershed depends on interaction of producing and retaining surface runoff among constituent ecosystems such as farmland,forest,grassland,etc.,of which grass or forest patches as parts taking surface runoff play an important role in soil and water conservation.The larger grass and forest coverage,the stronger the absolute control capacity of vegetation on soil erosion,or influencing factors about topography may not be ignored.This paper also analyses the definition of critical grass and forest coverage.It is indicated that critical grass and forest coverage have high values with large average slopes.If grass and forest coverage in a watershed gets above 50%,generally speaking,vegetation in it may check soil and water loss steadily and efficiently.Based on further analysis,it is considered that by using computer techniques and related maps,intensively researching into spatial pattern of vegetation can integratedly clarify the effect of vegetation as a whole on protecting soil from erosion, and meanwhile it is necessary to make an approach to retaining effect of vegetation patches on concentrated surface runoff which includes the runoff coming from other patches.

根据景观生态学的观点 ,对流域的产沙特征及其与林草植被的关系进行了探讨 ,表明流域土壤侵蚀状况是由其农、林、草地等生态系统之间产流与拦蓄两种作用相互影响的结果 ,其中作为地表径流滞纳区的林草植被斑块起重要作用。林草覆盖率越高 ,植被对侵蚀的绝对控制能力越强 ,否则流域地形因素的影响亦不可忽视。还分析了流域临界林草覆盖率的定义 ,表明临界林草覆盖率随其平均坡度的增大而增大。当流域林草植被整体覆盖率达 50 %以上时 ,植被可稳定高效地抑制水土流失。进一步分析认为 ,利用计算机技术并借助有关图件深入研究植被的空间格局才能完整阐明植被的整体防蚀作用 ,同时探讨植被斑块对富集叠加径流的滞纳作用也是必要的。
