Abstract
Ignoring the function of natural landscapes in the rapid development of urbanization, and especially in the conservation of historic urban landscapes, is still obvious today, and this has caused a large decrease in natural space, loss of habitats, and an increase in disasters. The resilience of a whole city and parts of it, such as historic urban areas where the historical process of man and nature have been recorded, as well as the interaction between nature, economy, and culture, is not strong enough to maintain the stability of urban ecosystems. It is misleading to think that the resilience can be built in a historic urban area without a natural landscape. We question whether this is true. Using a semantic differential analysis method from a historical perspective, this paper aims to answer this question through research on the correlation between resilience and man and nature through a case study of Yudai Trench historic urban landscape in Guangzhou, a historic urban area with 1000 years of history. A total of 212 pieces of evidence were extracted from 59 historical sources. The results showed that the cultural and economic conditions were in the same step and cycles as nature, which were influenced strongly by climate change, and that the natural landscape has a correlation on and is a dominant force in the resilience of historic urban landscapes.

This paper proposes four hypotheses that need to be tested: (1) the Yudai Trench historic urban landscape has resilience to climate change; (2) the natural, economic, and cultural systems have correlations; (3) the natural system has dominance and priority in the resilience change; (4) there is a limit to the resilience of natural landscapes
There are two kinds of changes in the three systems of the Yudai Trench historic urban landscape according to the changes in temperature (Figure 3)
Summary
In the face of natural, economic, and cultural urban development problems such as biodiversity loss, heat island effect, cultural fragmentation, and frequent occurrence of diseases [1,2,3,4,5,6,7], the 2030 Agenda for Sustainable Development of the United Nations has proposed that urban sustainable development should be “inclusive, safe, resilient and sustainable” [8]. How to improve the ecological resilience of cities, enhance the ability to cope with various external and internal impacts of cities, and promote sustainable urban development are major challenges facing cities around the world [9,10,11]. Urban landscapes are designed to stabilize urban resilience by addressing a wide range of environmental problems in cities and preventing sudden impacts [12,13,14]. In the context of climate change, if the complexity of urban landscapes is not accurately understood, irreversible damage to urban resilience will occur [15,16]
