Blocking the Sand Dust from Thousands of Miles Away! The "Blue Ecological Code" of China's Desertification Control

2025-04-23

Desertification Control by PV

China’s "Blue Ecological Code"

for Desertification Control

Since the beginning of this spring

Sichuan has experienced three rare sandstorm events

with most regions affected by the dust

The source of these sandstorms lies in

southern Mongolia and China’s northwestern regions

The area of desertified land in China

accounts for 26.81% of the country's total land area

With the global warming

and the aggravated ecological vulnerability of northern sand-source regions

the frequency of sandstorms moving southward continues to rise

Desertification control is no longer just a challenge for northern China

When sandstorms cross the Qinling Mountains

this "transboundary" dust

not only sounds an ecological alarm

but also pushes the issue of desertification control

into the national spotlight

Chinese PV enterprises are deploying innovative solutions

to build a "blue defense line" in the desert

generating electricity above the panels and fostering greenery beneath them

rewriting the ecological dilemma through PV-powered desert control

Part.1

PV Matrix

The Ecological Magic in the Desert

While traditional desert control

struggles in a cycle of "treatment-degradation-retreatment"

PV-powered desertification control innovatively

combines ecological restoration with clean energy

forming a triple governance mechanism

Physical Sand Fixation

PV panels effectively reduce ground wind speed

minimizing sand and dust uplift

Combined with straw checkerboard sand barriers

they stabilize shifting dunes

Ecological Restoration

The shading of the PV panels reduces water evaporation

shade-tolerant forage grasses and Chinese medicinal herbs are planted below the panels

and windbreak forest belts are planted between the panels

forming a three-dimensional ecological barrier

Economic Revitalization

PV power generation + drought-resistant cash crops + livestock farming

Diversified income streams boost local livelihoods

Keshiketeng Banner, Inner Mongolia

Datang Chifeng Keshiketeng Banner Hunshandake Sandland 100 MW PV Phase II Project

Located in Bayan Duhu Gacha, Darian Sumu, Keshiketeng Banner, this project not only boosts local economic development but also provides clean energy to support ongoing desert ecological restoration, significantly improving regional environmental quality.

Tongwei TNC 2.0

Adding New Green to the "PV Oasis"

Typically

desert surfaces have an reflectivity of around 30%

higher than ordinary ground (e.g., grasslands, soil)

which provides more reflected light for bifacial PV modules

At the technological level

Tongwei’s TNC 2.0 modules, utilizing Poly Tech technology

achieve a bifaciality rate of over 88%

(certified by TÜV Rheinland and CGC)

significantly enhancing rear-side power generation
