Figure shows the Cycling buffer analysis in Kai Kung Leng (travel in 15 mins) 圖顯示在雞公嶺中的單車分析（15 分鐘路程）

By the GIS buffer analysis, we can figure out that Kai Kung Leng is highly accessible in any directions, motorbike can easily traffic thought the west and east site by the connected secondary roads.

通過GIS緩衝區分析，我們可以看出雞公嶺在任何方向都非常容易到達，電單車可以通過連接的道路輕鬆通行到東西方。

You can try the interactive map to (1) choose the traffic mode, (2) choose the travel time or distance dimension and (3) click the place your want to know (draw buffer).

您可以嘗試交互式地圖來（1）選擇交通模式，（2）選擇旅行時間或距離維度，（3）單擊您想知道的地方（繪製緩衝區）。

The motorbike travels across the hill may leads over-tramping, soil compaction and intensifies leaching to the soil profile of Kai Kung Leng.

電單車穿越山丘可能會導致過度踩踏、土壤板結，並加劇對雞公嶺土壤剖面的浸出。

Soil compaction occurs when soil particles are pressed closer together, resulting in a reduction in pore space. The pore space is crucial because it allows air and water to circulate among soil particles, allowing plant roots to develop and give water and nutrients to plants.

In Kai Kung Leng, the motorbikes applies pressure to the soil damages the soil structure. Since then the soil has been compacted, it density has been increase. Soil beneath can cause tree and shrub decline or death, even in established trees. Because the roots of trees and shrubs cannot line the soil as securely as they formerly did, then trees collapse and die. The soil compaction thus causes vegetation decrease and even accelerates the weathering and erosion process. Because of the degraded trees offer a seeping agent and room for denudation to occurs, it comes to a vicious cycle in the end.

當土壤顆粒被壓得更近時，就會發生土壤壓實，從而導致孔隙空間減少。 孔隙空間至關重要，因為它允許空氣和水在土壤顆粒之間循環，使植物根係發育並為植物提供水分和養分。

在雞公嶺，電單車對土壤施加壓力會破壞土壤結構。 從那時起，土壤被壓實，密度增加。 下面的土壤會導致樹木和灌木衰退或死亡，即使是在已建立的樹木中也是如此。 由於樹木和灌木的根不能像以前那樣牢固地排列在土壤中，因此樹木會倒塌並死亡。 土壤板結因此導致植被減少，甚至加速風化和侵蝕過程。 由於退化的樹木提供了滲出和發生剝蝕的空間，最終陷入了惡性循環。

The New Territories Indigenous villagers "permitted burials area" policies includes many area that allows fire burning may increase the risk and frequency of hill-fire occurs in Kai Kung Leng. The Hong Kong government rarely check the "permitted burials" land, then leading the burials area has been enlarges illegally.

新界原居民「認可殯葬區」政策包括許多允許焚燒的區域，可能會增加雞公嶺山火發生的風險和頻率。香港政府很少檢查「認可殯葬區」，隨後導致墓地面積被非法擴大(香港01,2020)。

2) afforestation in the eroded minor trails 在被侵蝕的小徑上植樹

To heighten the effectiveness of regulating official hiking routes, afforestation can be ideal natural blockage for the people who doesn't follow the official hiking routes. It does not limited to become a blockage to guild people hike in major trails, but it can also rebuild the hillslope eco-system after hill-fire or over-tramping (soil compaction). Afforestation can protect the barren surface, the root of trees may help to grasp the surface soil layer and plant in the slope can blind the soil tightly, increasing the shear strength of the slope preventing landslide occurences as well.

為了提高規範官方徒步路線的有效性，植樹造林可以成為不遵循官方徒步路線的人的理想的自然障礙。 它不僅可以成為理想的自然障礙，還可以在山火或過度踩踏（土壤壓實）後重建山坡生態系統。植樹造林可以讓樹木有利於保護貧瘠的地表，樹木的根可以幫助抓住表層土層，在斜坡上種植植物可以緊緊地遮住土壤，增加斜坡的抗剪強度，防止山泥傾瀉事件的發生。
