Study On Plant Landscape Of Ji’nan Daming Lake

The paper focused on the plant landscape of Ji’nan Daming Lake scenic spot, and analyzed thedistribution of plant families and genera, the value of plant species, application frequency, the sizeorder structure, the height structure and the plant proportion, summarized the composition of plantspecies; analyzed the index of plant communities such as canopy density, diversity and similarity.Summarized the characteristics of plant communities; draw the plan of sample area and selected thetypical plant space types, analyzed the construction methods of every plant space type; evaluatedplant landscape of Ji’nan Daming Lake scenic spot by the Analytic Hierarchy Process. The quality ofplant landscape of Ji’nan Daming Lake is better, it shows diversity on the whole. The mainconclusions were as follows:1.22sample area were selected to investigate and used the inventory method, analyzed thecomposition of plant species, the results of the survey were as follows: Within the scope of theinvestigation, there were116kinds of plants belonging to46families and82genera, among them,there were5families,9genera and17species of gymnosperm,41families,73genera and99speciesof angiosperm, rosaceae had the most species that has15genera and41species. The tree species wererelatively drab within the community. The diameter order structure analysis of dominant species isconsiderable, but a majority of trees were mature. In the aspect of plant height, Ⅲ level plant species（3m＜H≤5m）should be increased. Evergreen plants of tree layer were slightly deficient, plants ofshrub layer were obviously deficient, plants of ground layer were more monotonous. Summerflowering species were fewer.2. Analyzed the diversity of plant communities of Ji’nan Daming Lake scenic spot from the indexof plant communities such as canopy density, diversity and similarity. the results of the analysis wereas follows: the canopy density index was overall high, the plant community type of sparse woodsgrass land was lack; the plant communities showed high diversity on the whole, the diversity of shrub layer was lower than tree layer; the repeatability of plant communities was smaller，especially theisland plant communities showed more lower similarity with other plant communities.3. According to combination of space constitute to classify the plant landscape space of DamingLake scenic spot, analyzed configuration concept and technique of plant landscape space. The resultsof the analysis were as follows: In Daming Lake scenic spot, the space scale was reasonable ofpartially open space of plant landscape, the height ratio of the upper, middle, and lower was about6.0:2.5:1, the ratio of planted area and lawns and paved area was about2:1. The space scaleof vertical plant landscape space was larger, the space utilization was low; but the treatment tovertical separation surface and base surface was better. The creation of plant landscape space wasmore successful. It meet the requirement of cover plant landscape space on the choice of plant speciesof tree layer and the treatment of coverage and vertical separation surface; but the way of growing ofshrub layer and grand layer plants corridor space of Zeng dyke need to be improved.4.80plant communities were elected to evaluated plant landscape of Ji’nan Daming Lake scenicspot by the Analytic Hierarchy Process, it showed that8communities were on the first grade,49communities were on the second grade,21communities were on the third grade and2communitieswere on the fourth grade. The evaluation result indicated that pant landscape quality of Ji’nan DamingLake scenic spot was good overall. But，in the construction of future， plant landscape culturalfunction and service function should be promoted.
