江西省泰和县的自然景观破坏程度共分为6级∶0.原生级;1.极轻微破坏级;2.轻微破坏级;3.中等破坏级;4.严重破坏级;5.极严重破坏级。 根据野外调查资料、土地利用现状图和航片按上述分级绘制泰和县山地丘陵自然景观破坏程度分级图,并根据该图量算出全县和各公社的各分级的面积。根据各分级的面积占总面积的百分数来评价研究地区山地丘陵的自然景观破坏程度和自然程度。 评价结果:泰和县的山地丘陵总的来看是中等破坏水平和准人为状态。县内各公社的破坏程度则与人口密度和地貌条件有密切关系,例如,桥头公社(人口较稀和以低山为主)的山地丘陵总的来说是极轻微破坏水平和准自然状态;冠朝公社(人口密度中等和以丘陵为主)的山地丘陵总的来说是严重破坏水平和人为状态;万和公社(人口较密和以低丘平原为主)的山地丘陵总的来说是极严重破坏水平和人为状态。
Taihe County, Jiangxi Province, the natural landscape damage is divided into six levels: 0. Primary level; 1. Very slight damage level; 2. Slight damage level; 3. Moderate damage level; 4. Serious damage level; 5. Very serious damage level. According to field survey data, land use maps and aerial photographs, the graded map of the destruction degree of the natural landscape in the mountainous hills in Taihe County was drawn according to the above classification, and the graded area of the county and each commune was calculated according to the figure. According to the graded area as a percentage of the total area to evaluate the study area of mountainous hills natural landscape damage and natural extent. Evaluation results: The mountain hills in Taihe County are generally moderately damaged and quasi-man-made. For example, the mountainous hills in the Qiaotou commune (the more populous and low-mountainous areas) are generally characterized by very light levels of damage and quasi-natural conditions; The mountainous hills of Corum (commune of medium density and hilly area) are generally badly damaged and man-made; mountainous areas of Maucao commune (densely populated and dominated by hilly plain) It is a very serious level of destruction and man-made state.
