Phylogenetic relationships of Dothideales and its allies were investigated based on analyses of nrDNA 18S (44 sequences of 31 species belonging to 20 genera) and 28S (41 sequences of 33 species belonging to 18 genera) partial sequences.

The monotypic genus Macrovalsaria previously of uncertain taxonomic position turns out to be a member of Botryosphaeriales and seems to be related to Botryosphaeria. The placement of Neopeckia and of Dothidotthia is in Dothideales and Botryosphaeriales, respectively. The genera Plowrightia and Botryosphaeria as currently defined are not monophyletic. Species of Plowrightia appear to be associated with three genera, Dothidea, Neopeckia and Sydowia; those of Botryosphaeria tested are recognized as three groups.

结果还显示，座囊菌纲中分类地位不确定的属Macrovalsaria与Botryosphaeria的关系相对接近，应该归于葡萄座腔菌目；历史上分类地位有疑问的Neopeckia和Dothidotthia两个属处于不同的目中，前者属于座囊菌目，后者为葡萄座腔菌目的成员；座囊菌目的Plowrightia属并非单系群，该属成员分别与Dothidea、Neopeckia和Sydowia三个属聚类在一起；现行的Botryosphaeria属也非单系群，其属的概念有待澄清。

The results indicate that the dothideomycetous genera tested are monophyletic and three lineages are recognized, i.e. Botryosphaeriales, Dothideales and Pleosporales; which supports the recognition of Botryosphaeriales as a separate order from Dothideales.

邻接法和简约法分析结果显示，座囊菌纲供试类群为单起源，形成三个独立的分支并获得较强的支持率，分别代表座囊菌目、葡萄座腔菌目和格孢腔菌目。

3Using long-term measurement of forest ecosystems, together with r elative data provided by forest resource inventory, hydraulic and meterorologica l departments, we estimate the various forest benefit values of Heilongjiang Pro vince, including those for visible and invisible products. Transferring the "pr oducts" to currency value using equivalent replacement of beneficial products f or currency and standard dimension, the total value is 498.687×108 yuan which takes up 32.7%of the total annual average provincial production (1522×108 yuan).

3引用多年森林生态系统定位研究结果，并参照森林资源调查、水利、气象等部门提供的有关数据，计算出黑龙江省森林各类效益值(有形产品和无形产品的产量)，通过等效益物替换和货币置换法进行&产品&的转换和量纲统一，最终得出黑龙江森林总效益值为498.687×108元，占全省(1990-1992)年平均总产值1522×108元的32.7%。
