### The Preference of Endowment Factors during PLES Transfer
#### 3.5.1 Decreasing Nature Process Results  
The transfer of ES-PS is mainly affected by elevation. Figure 10a shows the results. The contribution of elevation accounted for 59.53%, the contribution of the others was relatively average, and each of them accounted for less than 10%. When the elevation was lower than 800 m, the factors had a positive effect. In Figure 10b, after 500 m, the influence intensity gradually decreased with the increase of the elevation index. When it exceeded 800 m, the influence changed to negative. After 1250 m, the negative influence intensified. The ES was transformed into PS because the expansion of agricultural planting varieties had different demands for different climate and altitude conditions. As a result, it was difficult for a part of the original space for food cultivation to become the planting area for new crops due to climate reasons. In addition to this, the space of this type was mainly in the transition zone from the mountainous area to the plain area, which was closer to the concentrated area of LS. It could also meet the urban demand for agricultural products better.  
The process of ES-LS was mainly influenced by elevation, the distance to cities and the distance to roads (Figure 11a). The contribution rate of elevation was higher than 30%. The other two factors were higher than 20%. It is shown in Figure 11b that positive effects were observed in areas below 750 m, within 5 km of urban areas and 250 m of roads. Negative effects were observed in areas 250-3080 m from roads. ES-LS patches are mainly distributed next to the coastal line and around the mountain city. The ES area was abundant in the coastal region, but the usage of harbor resources accelerated the transformation process. Besides this, urbanization inspired ecological tourism demand from citizens, and ES around the mountains was developed. It formed many resorts combining ecology and life, which became one of the important sources of the ES-LS patches.

In Figure 12a, relief intensity and elevation are the main contributing factors for the transformation of PS-LS, with contributions of 57.21% and 33.21%, respectively. It can be seen that natural factors, especially topographic features, are the main reasons for the transferring process. The visualized marginal effect shows that the two factors played a positive role in the transformation process when the relief intensity was less than 70 m and the elevation was less than 1050 m (Figure 12b). The effect intensity peaked when the index

level was lower. Living functions are distributed at the flat and low-altitude area, and the priority of LS is higher than that of PS, so the PS at the edge of the living space is invaded.
