To all appearance the summer's pomp was still at fullest height, and although in the tilled acres green had given way to gold, though rowans were reddening, and the woods were dashed here and there with a tawny fierceness, yet light and warmth and colour were still present in undiminished measure, clean of any chilly premonitions of the passing year.

Historical sites: the southern slope of Kawamura Red-billed Hill, since the beginning of the spring of 1964, the provincial model workers Guo Shan, 23 after the Spring and Autumn Period, the practice of repeatedly and continuously explore, to create a land-for-drought level terrace renovation sik Tree technology, in order to move fortitude striking more than 42,000 cubic meters of earth, iron mill bald Catalpa low post and the first 17, 753 to renovate into a high-standard terraced fields, planting 125 acres, planted fruit, pears, peaches, apricots and other economic and elm trees, Chun, Huai Yang, pine and cypress trees, and other ecological 10,000 a total of more than 3.84, in the past so that the bald ridge of barren hills into a tree, pear fragrance of the landscape, Guo Shan as the "Red-billed the new hill-yu Public,"Red-billed Hill will be listed as one of the eight new Ning.

名胜古迹：南坡川村红嘴山，自1964年春开始，省劳动模范郭富山，历经二十三个春秋，反复实践，不断摸索，创造出抗旱换土水平梯田整修植树技术，以惊人的毅力移动土方42000多立方米，磨秃铁楸和橛头17把，修整成753块高标准梯田，造林125亩，栽种果、梨、桃、杏等经济树种和榆、椿、槐、杨、松柏等生态树种共3.84多万株，使过去的荒山秃岭变成了绿树成荫，梨果飘香的风景之地，郭富山被誉为&红嘴山上新愚公&，红嘴山被列为会宁新八景之一。

For the leaf area index of the three forest types, there was a similar variation trend, i.e ., increased first and decreased then, with the maximum presented in mid-July or August for Q. mongolica and J.mandshurica forests while in mid-August or September for F. rhynchophulla forest. The canopy porosity of the three forest types also had a similar variation trend, but opposite to leaf area index, being decreased first and increased then, with the minimum presented in mid-June, July, August or September. The analysis of variation coefficients of leaf area index, transmitted direct gap light, and transmitted diffuse gap light indicated that the spatial pattern of leaf area index in July-September was the main factor affecting the spatial distribution of transmitted diffuse gap light.

结果表明，3种林型的叶面积指数变化总体趋势是一致的，均呈先上升再下降的单峰曲线，蒙古栎林和胡桃楸林都是在7月中旬或8月中旬达到最大峰值，花曲柳林是在8月中旬或9月中旬达到最大峰值；3种林型冠层孔隙度的变化总体趋势也是一致的，呈先下降再上升的单峰曲线，不同样地峰值出现的时间也不同，最低峰值在6、7、8、9月中旬均有出现；通过对不同月份的叶面积指数、林下散射光、林下直射光的变异系数分析表明，7—9月叶面积指数的空间格局是影响林下散射光空间分布的主要因素。
